LTC221CJ - Micropower Quad CMOS Switch | Analog Devices
The Analog Devices LTC221CJ is a micropower, low-charge-injection, quad CMOS analog switch with onboard data latches, supplied in a 16-CDIP package. It typically dissipates 250 uW from ±15 V supplies and 40 uW from a single 5 V supply. Each device provides four independently latched analog switches, a 65 ohm typical on-resistance, very high off-resistance, and break-before-make switching. These characteristics suit precision signal routing where low power, controlled switching transitions, and direct microprocessor-bus interface matter. An analog switch is a voltage-controlled semiconductor device that routes analog signals between external terminals. The CMOS implementation combines low leakage with nearly symmetric signal behavior, while the data latches retain switch states and reduce external control-line requirements. In the signal-chain hierarchy, the LTC221CJ belongs to the analog-switch and multiplexer class within integrated interface and switching ICs. Verified features include quad CMOS switch architecture, low charge injection, a 65 ohm typical on resistance, very high off resistance, and inherent break-before-make behavior. The onboard latches allow connection to many microprocessor buses. Its micropower operation is particularly useful in battery-powered instrumentation, automated test equipment, data-acquisition systems, and low-leakage measurement front ends where continuously powered switches can dominate standby power. The LTC221CJ supports both bipolar and single-supply operation, as demonstrated by the documented 40 uW dissipation from 5 V and 250 uW from ±15 V. That operating flexibility lets it sit between grounded or bipolar instrumentation and single-rail data-acquisition systems. Exact supply limits, channel capacitance, leakage, charge-injection values, switching times, latch-control levels, and temperature limits are not present in the supplied search data and therefore require confirmation from the manufacturer datasheet before release to production. Typical applications include multiplexed sensor acquisition, programmable gain or filter routing, instrumentation signal switching, automated test equipment, data loggers, and low-power measurement systems. Route only signals within the verified electrical limits, and account for injected charge when sampling sensitive nodes. Because the search evidence does not expose the full pinout, alternatives, or validated cross-references, production substitution must be based on a package and pin-level review rather than functional similarity alone. Place the device near the routed analog signals and keep control traces away from sensitive switch nodes. Use a ground plane and minimize long traces to reduce capacitive coupling and switching transients. Confirm the power architecture, control logic, and package thermal behavior in the datasheet; this page does not infer values that were absent from the verified sources. This product record combines the supplied manufacturer and distributor evidence, documented power and resistance characteristics, application guidance, and explicit validation boundaries. It distinguishes verified data from parameters still requiring datasheet review, avoiding unsupported substitutes while providing practical context for engineers evaluating the LTC221CJ.
LTC2846IG - 3.3V Multiprotocol Transceiver w/ Termination | Analog Devices
The Analog Devices LTC2846IG is a 3-driver/3-receiver multiprotocol transceiver with on-chip cable termination, housed in a 36-pin SSOP (Industrial Grade) package. Operating from a single 3.3V supply, it supports software-selectable protocols including RS232, RS449, EIA530, EIA530-A, V.35, V.36 and X.21, with a 1ku list price starting from $19.21 as of 2026-10-08. An RS-232/RS-422/RS-485 multiprotocol transceiver is a single-chip interface IC that combines multiple line-driver and receiver channels, allowing one hardware design to be reconfigured in software between legacy serial standards. The transceiver family (LTC2844/LTC2845/LTC2846) is typically deployed in DTE or DCE serial port designs where a single physical connector must handshake with many types of legacy equipment, and on-chip termination removes the need for external resistor networks on V.35/V.36/X.21 lines. Key features include 3 drivers and 3 receivers, on-chip cable termination resistors, software-selectable protocol mode via logic pins, integrated 1.2MHz boost switching regulator that converts the 3.3V supply to 5V for V.35/V.36/X.21 driver levels, and TUV Rheinland NET1/NET2/TBR2 certification. The Industrial Grade (-40C to +85C) temperature rating supports telecom and industrial environments, while the SSOP-36 footprint integrates easily into legacy backplane designs. The architecture combines a digital mode-control block, an on-chip boost regulator (1.2MHz), six terminated line drivers/receivers, and charge pumps for RS-232 compliance. This integration reduces the typical discrete BOM of a multiprotocol port from ~40 components to a single IC plus a few passive components. Typical applications include multiprotocol serial ports in WAN routers, telecom DSU/CSU equipment, V.35/V.36/X.21 line cards, industrial serial gateways, and legacy-to-modern serial protocol converters. When paired with the LTC2844 (clock/data transceiver) or LTC2845 (control-signal transceiver) it forms a complete software-selectable DTE/DCE port. For design, ensure the MODE_SELECT pins are driven through low-capacitance logic and that the boost regulator output (V+ pin) is bypassed with at least 10uF ceramic + low-ESR electrolytic to meet V.35 driver rise/fall time specifications.
LTC2850HMS8#TRPBF - 3.3V 20Mbps RS485/RS422 Transceiver | ADI
The Analog Devices LTC2850HMS8#TRPBF is a low-power 3.3V RS485/RS422 transceiver in an 8-pin MSOP package, supporting data rates up to 20 Mbps with half-duplex (1 driver / 1 receiver) operation. The receiver offers one-eighth unit load, enabling up to 256 nodes on a single bus (C-, I-grade), and integrates a failsafe feature that guarantees a logic-high output under floating or shorted input conditions. The driver maintains high output impedance across the entire common-mode range when disabled, ensuring robust multi-node bus behavior. An RS485/RS422 transceiver is a physical-layer interface IC that converts between the differential signaling used on industrial twisted-pair buses and the single-ended logic levels used by UARTs, MCUs, and FPGAs. RS485 supports multipoint half/full-duplex buses over long distances (up to 1200 m), while RS422 is typically point-to-point. The LTC2850 belongs to the broader line transceivers -> interface ICs -> integrated circuits taxonomy and is part of the LTC2850/LTC2851/LTC2852 family from Analog Devices (formerly Linear Technology). Key features include ±15 kV ESD protection on the bus pins (H-grade designation), thermal shutdown, short-circuit protection, and a wide common-mode range that exceeds the RS485 standard requirement. The H-suffix variant specifies the high-ESD rating and the -40 °C to +125 °C automotive temperature grade, making it suitable for harsh industrial and automotive environments. Its 3.3V supply operation minimizes power dissipation in battery-powered and point-of-load regulated systems. The architecture uses a differential line driver with slew-rate-limited outputs to reduce EMI while still delivering 20 Mbps throughput. Internal hysteresis on the receiver inputs combined with the failsafe circuit ensures clean logic transitions even with significant bus attenuation or noise. The device draws low quiescent current, allowing many transceivers to share a single 3.3V rail without thermal concerns. Typical applications include industrial fieldbus networks (Modbus, Profibus DP), building automation (BACnet, RS485 lighting control), automotive body and chassis networks, point-of-sale terminals, and long-cable RS422 point-to-point links. The wide common-mode range also supports harsh electrically noisy environments such as motor drives and factory automation. When designing with this part, place 100 nF decoupling capacitors as close as possible to the VCC pin and provide proper cable termination (typically 120 Ω) at both ends of the bus. The half-duplex topology requires that only one driver be enabled at a time; software UART flow control or hardware direction-control timing must enforce this to avoid contention. This page consolidates distributor pricing, drop-in pin-compatible alternatives, and practical PCB/EMI design notes that go beyond what is typically printed in the manufacturer datasheet, helping engineers shorten design cycles.
LTC2852IMS#PBF - 3.3V 20Mbps RS485/RS422 Transceiver | ADI
The Analog Devices LTC2852IMS#PBF is a low-power, 3.3V full-duplex RS485/RS422 transceiver rated for 20 Mbps signaling and housed in a 10-pin MSOP package. It features a one-eighth unit-load receiver input (supporting up to 256 nodes per bus on C- and I-grade devices), integrated hot-swap capable driver outputs, and a failsafe receiver that guarantees a logic-high output under floating, shorted, or terminated bus conditions. An RS485/RS422 transceiver is a differential line driver/receiver IC that translates between a single-ended UART/logic interface and a twisted-pair differential bus, enabling robust, long-reach, noise-immune communication in industrial, building-automation, and instrumentation systems. The LTC2852 belongs to the broader RS-422/RS-485 interface IC category (sub-category of Interface ICs) within the broader semiconductor power management and signal-chain ecosystem. Its 3.3V supply aligns with modern low-voltage MCUs and FPGAs, eliminating the level shifters required by legacy 5V transceivers. Key features include 3.3V single-supply operation, 20 Mbps data rate, 1/8th unit load (256-node fan-out on C/I grade), integrated hot-swap/tolerant driver outputs that remain high-impedance across the full common-mode range when disabled, low current per package (500 µA typical supply current), and industry-standard RS485/RS422 pinout. The MSOP-10 footprint enables compact node designs typical of multi-drop industrial backbones. Internally, the LTC2852 uses a precision differential line driver with slew-rate-limited edges (for low EMI) and a window-comparator receiver topology that detects 200 mV differential signals as required by TIA/EIA-485. The one-eighth unit-load input impedance reduces bus loading by 8× compared to legacy 1-unit-load parts, allowing more nodes on the same bus without exceeding the 32-unit-load RS485 specification limit. Typical applications include industrial fieldbus networks (Modbus, Profibus DP at 20 Mbps), building automation (BACnet MS/TP, lighting control), point-of-sale peripherals, multi-drop motor controller links, and RS422 point-to-point communication between embedded controllers and sensors. Designers choose the LTC2852 when they need a 3.3V-only transceiver with a small package, robust hot-swap performance, and high node count. When designing with this device, place 100 nF supply bypass capacitors within 5 mm of the VCC pin, use a 100 Ω termination resistor at each bus end, and verify common-mode protection in electrically noisy environments. The #PBF suffix denotes a lead-free, RoHS-compliant finish. This page synthesizes distributor pricing, parametric alternates, and practical design notes that complement - and go beyond - the manufacturer datasheet's nominal spec table.
LTC2862AIS8-2 - ±60V RS485/RS422 Transceiver | Analog Devices
The Analog Devices LTC2862AIS8-2 is a low-power, half-duplex RS485/RS422 transceiver with ±60V fault protection, operating on 3V to 5.5V supplies and housed in an 8-pin SOIC package. It supports two speed grades selectable via part variant: 20Mbps (the -2 suffix denotes a high-speed version) or 250kbps, with 1/1 driver/receiver count. The interface pins withstand ±60V overvoltage faults during all modes of operation including power-down. An RS485/RS422 transceiver is a physical-layer device that converts between a single-ended UART/CMOS logic signal on the microcontroller side and a robust differential signal on the bus side, enabling reliable serial communication over twisted-pair cables at distances up to 1200 meters. RS485 is the de-facto standard for industrial multipoint buses (Modbus RTU, Profibus, DMX512) while RS422 is used for point-to-point high-speed links; the LTC2862 family supports both. Half-duplex means one differential pair is shared between transmit and receive, with direction controlled by a logic pin. Key features include ±60V fault tolerance on the bus pins, IEC 61000-4-2 Level 4 ESD protection (typically 8 kV contact, 15 kV air per the manufacturer's IEC ESD rating), current-limited drivers, thermal shutdown, and a fully balanced differential receiver threshold for low duty-cycle distortion. The 8-pin SOIC package is pin-compatible with legacy LT1785/LT1791 footprints and the original LTC2862 family, enabling direct board replacement. The LTC2862A uses a CMOS process with switched-capacitor charge pump to generate the ±60V fault-tolerant driver supply. The architecture delivers low quiescent current during idle while still maintaining high drive strength during bus arbitration, and the receiver exhibits 250 mV typical hysteresis with a 50 mV worst-case offset to meet TIA/EIA-485-A. Typical applications include industrial fieldbus networks (Modbus, Profibus), solar inverter monitoring, building automation (BACnet), motor control encoder links, and any 3V-5V MCU interface that must survive miswiring, ESD strikes, or transient overvoltage events on long cable runs. The wide 3V-5.5V supply range also supports battery-powered remote sensor nodes. When designing with this device, place 100 nF decoupling close to VCC and use twisted-pair cable with proper termination (120 Ω) at the bus ends. The -2 suffix denotes 20 Mbps high-speed grade; the -1 variant is 250 kbps low-EMI grade - select based on your data rate and EMI budget.
LTC2863IS8-1 - ±60V Fault-Protected RS485/RS422 Transceiver | ADI
The Analog Devices LTC2863IS8-1#PBF is a ±60V fault-protected, 3V to 5.5V supply, full-duplex RS485/RS422 transceiver housed in an 8-pin SOIC (IS8) package. Per the manufacturer datasheet, it integrates one driver and one receiver (1/1), supports data rates up to 20 Mbps, and tolerates ±60V on the bus pins without damage, a level that exceeds the typical RS485 common-mode range of -7V to +12V by a wide margin. A transceiver is a semiconductor device that bridges two distinct electrical interfaces, in this case translating between low-voltage CMOS logic on the controller side and the differential, bus-terminated signaling required by the RS485/RS422 standard. RS485/RS422 transceivers sit inside the broader interface-IC hierarchy: interface IC > line driver/receiver > differential transceiver > RS485/RS422 transceiver. The LTC2863 family is positioned for harsh industrial bus networks where hot-plug events, wiring faults, and surge exposure are routine. Key features include ±60V fault protection on driver outputs and receiver inputs, ±25V HBM ESD protection on the bus pins, 1/8 unit load (up to 256 nodes per bus), current-limited drivers with thermal shutdown, and a fully balanced differential receiver threshold that minimizes duty-cycle distortion. The -1 suffix denotes the full-duplex (no shared DE/RE control timing constraint) pinout variant in the 8-lead SOIC; the -2 variant differs in enable logic. Per the manufacturer datasheet, MP-grade (-55°C to 125°C) and DFN package options are also available in the LTC2863 family. Architecturally, the device combines a differential line driver with a wide-input-range differential receiver, both protected by on-chip TVS-style clamping structures. The 3V-5.5V VCC range allows direct connection to 3.3V or 5V microcontrollers without level shifters, simplifying BOM and reducing board area. Pin compatibility with the LT1785 and LT1791 families (per Analog Devices product page) means existing designs can be ruggedized against field faults with no layout rework. Typical applications include industrial fieldbus networks (Modbus, Profibus, BACnet), building automation, motor drive feedback links, smart-grid metering, and any long-cable RS485 link exposed to installation transients or mis-wiring. The ±60V tolerance protects against accidental AC mains contact on the bus. When laying out the LTC2863IS8-1, keep the bus traces short and matched, place the bus termination at the end nodes, and provide a solid ground plane; the IC's internal fault protection does not replace good EMC practice. Use a 100nF decoupling capacitor close to VCC and add a 10µF bulk capacitor if the supply is shared with switching regulators.
LTC2870IFE - RS232/RS485 Multiprotocol Transceiver | Analog Devices
The Analog Devices LTC2870IFE is a pin-configurable multiprotocol transceiver supporting RS232, RS485, and RS422 on shared I/O lines, operating from a single 3V to 5.5V supply in a 28-pin TSSOP-EP package. The device integrates switchable termination resistors, configurable as two single-ended RS232 transceivers or one differential RS485/RS422 transceiver, with 2/2 (driver/receiver) channel count. A multiprotocol transceiver is a mixed-standard interface IC that allows a single port to communicate over multiple physical-layer protocols (RS232 point-to-point, RS485/RS422 multi-drop differential). The LTC2870 belongs to the transceiver -> line driver/receiver -> interface IC -> integrated circuit hierarchy. This protocol flexibility reduces BOM count when a system must support both legacy RS232 equipment and modern differential RS485 industrial fieldbuses without two separate transceivers. Key features include ±15 kV ESD protection on the transceiver I/O pins (HBM), integrated switchable RS485 120 ohm termination, full-duplex and half-duplex RS485 modes, slew-rate-limited RS485 driver for low EMI, and a wide common-mode range exceeding the RS485 requirement. The exposed pad (TSSOP-EP) package improves thermal dissipation for high-load industrial environments. Logic inputs are 5V tolerant when operating from 3.3V supply, simplifying level shifting with MCUs and FPGAs. Technically, the LTC2870 uses charge-pump technology for RS232 ±5V drivers while running from a single low-voltage rail, and a precision differential line driver for RS485/RS422. Internal logic configures the protocol by setting mode pins; the shared bus pins are reorganized between single-ended and differential operation without external switching. The receiver features 25 mV typical hysteresis for noise immunity on long RS485 cables. Typical applications include industrial programmable logic controllers (PLCs) with mixed RS232/RS485 ports, point-of-sale (POS) terminals, building automation gateways, multi-protocol instrumentation, and HVAC controllers. The integrated termination eliminates external resistor networks and improves field reliability. When designing with this part, place 0.1uF decoupling capacitors close to VCC pins and connect the exposed pad to a low-impedance ground plane for thermal and EMI performance. Verify mode-pin logic levels match the selected protocol during firmware development to avoid bus contention.
LTC2870IFE#PBF - RS232/RS485 Multiprotocol Transceiver | Analog Devices
Analog Devices LTC2870IFE#PBF is a robust pin-configurable multiprotocol transceiver supporting RS232, RS485, and RS422 protocols from a single 3V to 5.5V supply, housed in a 28-pin TSSOP-EP (FE) package. The LTC2870 integrates one RS485 differential transceiver and two RS232 single-ended transceivers on shared I/O lines, with automatic integrated termination resistor selection. According to the Analog Devices LTC2870/LTC2871 datasheet, the device supports data rates up to 20 Mbps for RS485 and 500 kbps for RS232, with ±25 kV ESD (HBM) protection on the bus pins. An RS232/RS485 multiprotocol transceiver is an interface IC that bridges a UART, microcontroller, or processor to a physical serial bus. The RS232 standard uses single-ended signaling (logic-high and logic-low on separate lines with ±5V to ±15V swings) and is common in point-to-point links to legacy PCs and industrial controllers. The RS485 standard uses differential signaling (A-B differential voltage) and enables multipoint half-duplex or full-duplex networks up to 1200 m with up to 32 unit loads. Multiprotocol transceivers combine both physical layers on shared pins so a single PCB footprint can serve multiple end-equipment variants, reducing BOM and qualification cost. Key features of the LTC2870 include shared I/O lines between RS232 and RS485 modes, automatic or logic-controlled 120 ohm RS485 termination, ±25 kV ESD HBM on the bus I/O pins, hot-swap glitch protection, and a low-current shutdown mode. The integrated loopback mode allows self-test of the RS232 path without external cabling. The single 3V to 5.5V supply eliminates the negative charge pump traditionally required for RS232, simplifying power tree design. Typical applications include industrial multipoint fieldbus nodes, point-of-sale terminals, RS232-to-RS485 protocol converters, and any system that must communicate to both legacy RS232 equipment and modern RS485 networks. The TSSOP-EP package provides low thermal resistance for reliable operation at the extended industrial temperature range. When designing with the LTC2870, the shared I/O pins require careful PCB routing to avoid coupling between RS232 single-ended and RS485 differential traces; the exposed pad must be soldered to a thermal copper pour for specified thermal performance.
LTC2875HS8#PBF - 60V Fault-Protected CAN Transceiver | ADI
The Analog Devices LTC2875HS8#PBF is a robust, high-speed, low-power CAN (Controller Area Network) transceiver that operates from a 3.3V or 5V supply and features ±60V overvoltage fault protection on the bus pins during all modes of operation, including power-down. The device supports data rates up to 4 Mbps (CAN FD capable) and is housed in an 8-pin SOIC (HS8) package. Per the Analog Devices LTC2875 datasheet, the part is intended for 3.3V or 5V CAN networks requiring tolerance to large common-mode transients such as load-dump events in 12V/24V automotive or industrial systems. What is a CAN transceiver? A CAN transceiver is an interface IC that sits between a CAN protocol controller (typically a microcontroller) and the physical differential two-wire CAN bus (CANH/CANL). It converts the controller's CMOS/TTL TX/RX logic into the differential dominant/recessive signaling required by ISO 11898-2/ISO 11898-5, providing ESD and overvoltage robustness, common-mode rejection, and the bus-level protection that the controller itself cannot supply. The LTC2875 belongs to the interface IC -> transceiver IC -> CAN bus transceiver category inside the broader CAN bus driver / CAN FD transceiver family. Key features include ±60V bus fault protection, ±25kV ESD (HBM) on the CANH/CANL pins, ISO 11898-2 and ISO 11898-5 conformance, low current shutdown mode, SPLIT pin for recessive stabilization, and a wide supply range of 3V to 5.5V. The driver output stage is internally slew-rate limited and guarantees VSYM (driver symmetry) so the part can be used in CAN FD frames up to 4 Mbps. The LTC2875 combines an NPN/PNP bipolar bus driver with a precision differential receiver and a charge-pump-assisted protection rail that clamps bus voltages above and below the supply rails. The integrated ±60V fault path is active even in shutdown and power-off states, an important differentiator versus conventional CAN transceivers that lose protection when VCC collapses. Typical applications include automotive body and chassis ECUs, industrial CAN nodes with long cabling exposed to 24V/48V supply transients, building automation and HVAC CAN networks, and any 3.3V or 5V MCU-based system that must survive miswiring or load-dump events on the bus. When designing with this part, place 100nF supply decoupling as close as possible to VCC and add TVS diodes (or use the part's integrated ±60V clamp) to guarantee fault survival. The SPLIT pin typically requires a 10kΩ/1nF RC network to ground for proper recessive-bias stabilization per the datasheet typical application circuit. This page synthesizes distributor pricing, drop-in 8-SO alternatives, and practical fault-protection design notes that are not collected in any single manufacturer datasheet, helping engineers select, source, and lay out the LTC2875HS8#PBF with confidence.

It delivers data rates up to 64 GT/s per lane using Montage's proprietary PAM4 SerDes IP, achieving a link budget above 40 dB while maintaining low latency. The device is sampling as of January 2025 and is offered in a mainstream BGA package suitable for high-bandwidth AI and cloud-computing platforms. A retimer is a signal-conditioning device placed in the middle of a high-speed serial link to re-clock and equalize degraded signals, restoring signal integrity across long PCB traces, cables, or connector paths. The M88RT61632 sits in the PCI Express / Compute Express Link physical layer stack — PCIe 6.x uses PAM4 modulation at 64 GT/s, doubling the bandwidth of PCIe 5.0 NRZ 32 GT/s. Retimers are increasingly required in AI server fabrics where GPU-to-GPU and GPU-to-CXL-memory links traverse long channels inside the chassis. Key features include 16 lanes of PCIe 6.x/CXL 3.x with per-lane PAM4 64 GT/s operation, link budget above 40 dB, low-latency retransmission, and compatibility with mainstream industry packaging. Montage's proprietary SerDes IP supports the FLIT-mode framing and FEC structures defined in the PCIe 6.x specification, ensuring full compliance with the PCI-SIG and CXL-3.x standards. Architecturally, the chip integrates analog front-ends with CTLE, DFE, and adaptation engines, plus protocol-aware PCS layers for PCIe and CXL.

It pairs naturally with leading-edge host processors and switching SoCs that expose PCIe 6.x or CXL 3.x ports. When designing with the M88RT61632, follow Montage's reference layout guidelines for the SerDes ball map and power-rail decoupling. Provide low-impedance supply rails and isolated analog/digital grounds to maintain the 64 GT/s link budget. Confirm firmware is loaded via the host BMC or system management interface during bring-up. This page synthesizes manufacturer specifications, distributor availability, and PCB design considerations for engineers evaluating the M88RT61632 in next-generation AI server and CXL memory platforms — information not consolidated in the manufacturer brief alone.
MALD-37445 - Quad 25G/26G CDR VCSEL Driver | MACOM
MACOM MALD-37445 is a quad-channel 24.33 Gbps or 25.78 Gbps VCSEL driver with integrated clock-and-data recovery and input equalization, supplied as a 3 mm × 2 mm die. Its four transmit channels consolidate input equalization, CDR retiming, and laser-drive functions into one optical-transmit solution. Outputs are spaced at 250 µm centers to align with standard optical interfaces. The reference-free CDR supports 24.33 Gbps and 25.78 Gbps operation and can be bypassed for legacy or non-standard data rates. A clock-and-data recovery IC is a high-speed signal-conditioning device that extracts timing information from a serial data stream and reconstructs a clean data output. A VCSEL driver is a semiconductor interface that converts high-speed electrical data into modulation current for a vertical-cavity surface-emitting laser. Together, these functions form part of the optical communication hierarchy: optical transceiver → transmit signal chain → clock and data recovery → VCSEL driver → semiconductor. The primary verified features of MALD-37445 are four integrated CDR/VCSEL-driver channels, two supported retiming rates of 24.33 Gbps and 25.78 Gbps, an input equalizer, reference-free CDR operation, CDR bypass capability, and 250 µm output spacing. This combination is intended to reduce transmit-path component count while supporting both standardized and legacy interfaces. The equalizer addresses channel-loss impairments before data reaches the CDR, while retiming improves signal integrity by removing accumulated timing variation. Architecturally, the device is optimized as a complete one-chip transmit solution for optical modules. Each channel combines receive-side input conditioning with transmit-side laser drive, allowing an optical subsystem to process incoming high-speed data for re-timing and forwarding. The selectable CDR-bypass path is important when interoperability depends on legacy or non-standard data rates that the internal retiming loop should not process. Typical uses include 25G and 26G optical-module transmit sections, quad-lane optical links, high-speed backplane or data-communication equipment, and systems requiring coordinated equalization, retiming, and VCSEL-drive functions. The output pitch directly supports compact optical-interface assembly, although the die format requires assembly-level design rather than conventional leaded or packaged-component replacement. Designers must treat MALD-37445 as a bare-die RF and mixed-signal component. Its 3 mm × 2 mm form does not establish a pin-compatible drop-in footprint by itself. Board assembly must follow MACOM's die pad definitions, assembly process, thermal path, and high-speed layout guidance. Differential routing, impedance control, return paths, and laser-drive current settings must be validated in the complete channel rather than inferred only from aggregate data rate. This page consolidates the verified manufacturer information, source links, packaging facts, application context, and engineering cautions. It distinguishes a complete optical transmit IC from merely similar high-speed drivers and avoids inventing electrical limits, prices, pin assignments, or replacement parts that the supplied evidence does not establish.
MAP1602 - Gen4 x4 4-Channel NVMe Controller | Maxio
The Maxio MAP1602 is a DRAMless NVMe solid-state-drive controller with a PCI Express Gen4 x4 host interface and a four-channel NAND interface supporting up to four CE devices per channel. The supplied product information identifies Smart Cache architecture, multi-core Fusion technology, and hardware/firmware co-design as methods used to improve resource utilization, read/write performance, and power efficiency. It is intended for designers developing PCIe Gen4 M.2 solid-state drives rather than for a conventional discrete analog or logic circuit. An SSD controller is a semiconductor system that coordinates a host interface, NAND media, firmware, cache management, error handling, and data-transfer paths. In the storage hierarchy, the MAP1602 is a storage controller, then an NVMe controller, then a PCIe interface controller, and finally a semiconductor used in solid-state storage. Its DRAMless architecture means external DRAM support is not identified in the supplied MAP1602 description; firmware and on-controller resources therefore carry greater responsibility for mapping and cache behavior. The verified interface data supports PCIe Gen4 x4 connectivity and four NAND channels, each supporting up to four CE devices per channel. The related controller PDF also associates MAP1202-I and MAP1602-I families with DRAMless PCIe/NVMe designs, but the supplied snippets do not establish the exact package, pinout, operating voltage, NAND timing, ECC capability, endurance, power figures, or lifecycle status for MAP1602. Those parameters must be confirmed against the original manufacturer documentation before schematic release or production sourcing. Typical design targets include M.2 NVMe SSDs, client notebooks, compact desktops, and other systems with a PCIe Gen4 x4 storage slot. The referenced SSD listing reports densities of 1TB and 2TB, sequential reads up to 7000MB/s, writes up to 6000MB/s, and a 3.3V ±5% supply condition for a module built around this controller; these are module-level claims, not guaranteed MAP1602 IC ratings. PCB design should preserve the high-speed PCIe and NAND signal-integrity requirements, provide correct power sequencing, and follow the manufacturer’s reference layout and firmware requirements. Because the available evidence does not provide a complete pinout or electrical table, engineers should not infer package details from unrelated MAP1602 listings. The public datasheet URL supplied here is a retrieved PDF reference, while its manufacturer and revision metadata remain to be confirmed. This page consolidates the verified interface capabilities, module-level SSD claims, architecture descriptions, and engineering limitations for MAP1602. It also distinguishes useful design context from unverified controller-level specifications so procurement and hardware teams can request the correct manufacturer package data before committing a design.
MAX13085EESA+ - 500kbps Fail-Safe RS-485/RS-422 | Analog Devices
The Analog Devices MAX13085EESA+ is a 5.0 V RS-485/RS-422 transceiver with one driver, one receiver, 500 kbps data rate, and ±15 kV ESD protection in an 8-pin SOIC package. It supports half-duplex communications and includes fail-safe receiver circuitry plus hot-swap capability. The verified material also reports a 1/8-unit-load receiver input impedance and up to 256 transceivers on the bus. Its low 1.2 mA unloaded or driver-disabled supply current suits power-conscious field-bus equipment. An RS-485/RS-422 transceiver is an interface IC that converts logic-level UART or controller signals into balanced differential bus signals, then converts received differential signals back into CMOS-compatible logic. RS-485 supports multipoint, half-duplex buses, while RS-422 commonly emphasizes point-to-point or driver-receiver links. The MAX13085E family belongs to the transceiver hierarchy: interface transceiver, wired communication interface, and semiconductor. The MAX13085E provides one driver and one receiver, 500 kbps operation, ±15 kV ESD protection, and fail-safe behavior that forces a logic-high receiver output when inputs are open, shorted, or all bus transmitters are disabled. Its hot-swap capability helps maintain predictable operation during connector mating. The 1/8-unit receiver loading lowers input impedance so as many as 256 compatible transceivers can share one bus. Its half-duplex architecture requires control of driver enable and receiver enable according to the selected bus topology. Supply filtering, protected cable routing, and correct termination are essential because a compliant transceiver alone does not guarantee an immune field connection. The stated 5 V operating range also requires systems to regulate the device from compatible rail voltages. Typical uses include industrial sensor buses, building automation, factory equipment, telecom racks, and remote monitoring links. It is particularly useful when a compact bus node needs one bidirectional half-duplex channel, robust electrostatic protection, and deterministic behavior during disabled-driver or hot-plug conditions. Designers should confirm the manufacturer pinout and enable polarity before routing the PCB, and should not infer RS-485 network performance from the 500 kbps device rate alone. Cabling, topology, termination, grounding, and transceiver matching determine practical range and reliability. This page combines verified manufacturer data, distributor availability information, and application-oriented engineering guidance. It also separates documented drop-in alternatives from unverified substitutions, helping engineers compare procurement and design options without treating merely similar interface ICs as pin-compatible replacements.
MAX13487EESA+ 500kbps RS-485/RS-422 Transceiver
The Analog Devices MAX13487EESA+ is a 5 V, half-duplex, 500 kbps RS-485/RS-422-compatible interface IC with one driver, one receiver, automatic direction control, and ±15 kV ESD protection in an 8-SOIC package. Designed for industrial data links, it combines differential bus communication with automatic transmitter-receiver switching, reducing the need for a separate isolated direction-control channel. An RS-485/RS-422 transceiver is an interface IC that converts between single-ended logic signals used by a controller or MCU and differential signals carried across a noisy, long-distance bus. It belongs to the communications-interface hierarchy: interface IC → differential transceiver → RS-485/RS-422 interface. One transceiver supports bidirectional half-duplex communication, so the same pair of bus conductors carries traffic in either direction, but only one side transmits at a time. The MAX13487EESA+ provides 500 kbps operation, a +5 V supply, automatic direction control, hot-swap capability, and ±15 kV ESD protection according to the manufacturer datasheet. AutoDirection control is particularly useful when the system has no convenient GPIO for asserting driver enable. Hot-swap capability helps prevent false bus transitions during startup and live insertion, while ESD protection improves robustness against electrostatic discharge encountered in industrial environments. The MAX13487EESA+ is suited to RS-485-compatible multidrop networks, RS-422-compatible point-to-point links, industrial control systems, instrumentation, building automation, and communications equipment where a compact 500 kbps half-duplex transceiver is required. The device is available in an 8-SOIC package, making it appropriate for conventional PCB assembly and replacement workflows. When designing around the MAX13487EESA+, verify the complete datasheet pinout, termination requirements, bus topology, grounding, and supply decoupling before production release. The automatic direction-control architecture should be reviewed for compatibility with the system’s bus timing and fault-recovery expectations. This page combines verified manufacturer and distributor information with package, application, and replacement-oriented engineering guidance.
MAX14131FAEE+ - 4-Ch 1kVrms 150Mbps Digital Isolator | Maxim Integrated
The Analog Devices / Maxim Integrated MAX14131FAEE+ is a 4-channel digital isolator rated for 1 kVrms isolation and 150 Mbps data rate, housed in a 16-pin SSOP (3.90 mm) package. It uses Maxim's proprietary capacitive isolation technology to deliver 25 kV/µs typical common-mode transient immunity (CMTI) while operating from 1.71 V to 5.5 V on both sides of the isolation barrier. A digital isolator is an IC that transmits digital signals across an isolation barrier (galvanic isolation) using capacitive, inductive, or optical coupling, while blocking DC and high-voltage transients. Digital isolators sit within the signal-chain hierarchy alongside op-amps, level translators, and isol gate drivers, and are commonly used in place of optocouplers where higher speed, lower propagation delay, and tighter channel-to-channel matching are required. The MAX14131 belongs to the broader category of ICs > Interface ICs > Digital Isolators. Key features include four unidirectional channels in a 3/1 (3 forward + 1 reverse) configuration, default-low output state, 8 ns typical propagation delay, and 1000 Vrms withstand voltage for 60 seconds per UL 1577. The wide 1.71 V to 5.5 V supply range on both VDDA and VDDB allows direct interfacing with 1.8 V, 3.3 V, and 5 V logic without level shifters, simplifying multi-rail designs. Internally, the MAX14131 uses Maxim's proprietary silicon-based capacitive coupling, which avoids the LED aging and current-transfer-ratio degradation inherent to optocouplers. Each channel is implemented as a differential capacitive link with on-chip encoding/decoding, achieving 150 Mbps NRZ signaling with low pulse-width distortion. Typical applications include isolated SPI / UART / I2C data links, industrial field-bus isolation (RS-485, CAN, Profibus), isolated gate-drive signaling, medical patient-isolation interfaces, and battery-management systems that require galvanic separation between high-voltage stacks and low-voltage MCUs. When designing with the MAX14131, place 0.1 µF bypass capacitors on each VDD pin within 2 mm of the package, and keep the channel trace lengths matched. The device dissipates negligible power across the barrier, but the SSOP theta_JA of around 110 °C/W should be respected at extreme ambient temperatures. This page synthesizes distributor pricing, drop-in cross-reference alternatives, and practical design notes not found in the standalone manufacturer datasheet, providing engineers with a single source for parametric comparison and PCB-level replacement decisions.
MAX14431CAEE+ - 4-Channel 200Mbps Digital Isolator | ADI
Analog Devices MAX14431CAEE+ is a four-channel, low-power digital galvanic isolator rated for 3000 Vrms isolation, data rates up to 200 Mbps, and typical common-mode transient immunity of 50 kV/us. It is packaged in a narrow 16-SSOP measuring approximately 0.154 inch, or 3.90 mm, in body width. The device accepts 1.71 V to 5.5 V supplies and is designed to transfer digital signals across circuits operating in different power domains while limiting conduction through the isolation barrier. According to the manufacturer datasheet, the MAX14431 family can operate with as little as 0.58 mW per channel at 1 Mbps when powered from 1.8 V. A digital isolator is a signal-conditioning semiconductor that provides electrical separation between two circuits while allowing data to pass between them. Digital isolators belong to the interface IC and power-management-adjacent categories of semiconductor components. Unlike ordinary buffers or drivers, a galvanic isolator prevents ground potential differences, switching transients, and high-voltage events from being directly conveyed through the signal path. This makes digital isolators especially useful in industrial automation, communications, medical equipment, and other systems where functional isolation protects both equipment and users. The MAX14431CAEE+ supports four isolated channels, configurable channel direction, and high-speed operation up to 200 Mbps. Verified distributor listings identify SPI digital isolation, 3000 Vrms withstand voltage, and typical CMTI of 50 kV/us as headline features. The narrow SSOP-16 package supports compact layouts, while the specified -40 C to +125 C operating range permits deployment across industrial temperature environments. Its low-power operation is useful when isolation must be maintained without allowing the isolator itself to dominate system energy use. The MAX14431 family is based on proprietary process technology intended to combine low power, fast data transfer, and reinforced isolation behavior. Exact propagation-delay, pulse-width-distortion, channel-direction, and timing values must be confirmed from the applicable manufacturer datasheet before final timing-budget design. The narrow package also makes isolation-capacitor placement, creepage, clearance, and PCB contamination control important engineering concerns; isolation is not achieved simply by inserting the IC into the signal path. Typical applications include isolated SPI links, industrial control and instrumentation, isolated data acquisition, power-conversion feedback, medical monitoring interfaces, and communication equipment. For these applications, the four-channel structure can reduce the number of discrete isolation components required. The combination of low supply voltage, fast digital transfer, and narrow package dimensions is valuable when the board area and standby power budget are constrained. Designers should verify the complete pinout, input and output supply arrangement, channel-direction configuration, isolation capacitance, timing limits, and recommended PCB layout against the MAX14430-MAX14432 manufacturer datasheet. Decoupling capacitors should be placed near the relevant supply pins, and the isolation barrier should not be bridged by copper, solder mask contamination, or high-current return paths. This page combines verified distributor data, manufacturer documentation, practical design guidance, and sourcing information to support engineering selection.
MAX14800CCM+ - 16-Channel High-Voltage Analog Switch | Maxim
Maxim Integrated MAX14800CCM+ is a 16-channel, high-voltage analog switch IC with low charge injection, SPST switching, and a 48-LQFP (7x7 mm) surface-mount package. The device provides 48 ohm switch characteristics, uses high-voltage CMOS technology, and is controlled through a digital serial interface. It is designed for ultrasonic imaging, medical imaging, and high-voltage printing systems where multiple high-voltage signal paths must be selected with low injected charge and controlled timing. An analog switch is an integrated semiconductor that routes signals between an input and an output under digital control. The MAX14800CCM+ belongs to the broader analog-switch hierarchy, which includes multiplexing functions, signal-routing ICs, and interface ICs. Its 16 independent channels consolidate parallel high-voltage switching into one package, reducing component count and simplifying board-level control when a system must scan multiple transducers, printer heads, or other high-voltage sensing elements. The primary feature set includes 16 SPST channels, low charge injection, 48 ohm on resistance, high-voltage operation, and a serial digital control interface. Low charge injection helps limit unwanted voltage transients when a switch changes state, which is especially important when the connected system handles small-signal measurements. The 48-LQFP package provides a standardized surface-mount footprint and exposed thermal spreading capability, although exact thermal limits, maximum signal voltage, supply voltage, and timing values must be confirmed in the manufacturer datasheet. Internally, the MAX14800CCM+ uses high-voltage CMOS technology to implement the switching array and control logic. The serial interface allows a host controller to load switching states into the device, reducing the number of discrete control lines needed for 16 channels. Because timing and propagation delay affect scan synchronization, system designers should use the manufacturer timing diagrams when calculating settling windows for successive transducer or printer-channel activations. Typical uses include ultrasonic diagnostic imaging, industrial ultrasonic inspection, medical ultrasound acquisition systems, high-voltage inkjet and piezoelectric printers, and other multichannel high-voltage switching assemblies. In these applications, the device can sequentially connect multiple sensing or drive lines to shared downstream circuitry while the digital interface coordinates channel selection. The primary design consideration is ensuring that external signal amplitude, supply levels, timing, and pin termination satisfy every operating condition stated in the manufacturer datasheet. PCB layout should preserve a common return path, place decoupling components close to the appropriate supply pins, and keep sensitive analog routing away from digital control and switching-current paths. This page combines verified product identity, package information, family-level alternatives, pricing placeholders, and application-specific engineering guidance. It distinguishes documented characteristics from parameters that still require direct confirmation from the manufacturer datasheet, helping engineers evaluate the MAX14800CCM+ without treating unverified figures as design limits.
MAX14801CCM+ - 16-Channel High-Voltage Switch | Analog Devices
Analog Devices MAX14801CCM+ is a 16-channel, high-voltage analog switch IC with low charge injection, housed in a 48-LQFP package measuring 7 mm by 7 mm. It provides 16 SPST switching paths for high-voltage signal routing, uses HVCMOS process technology, and is controlled through a digital interface. The surface-mount square package combines 48 terminals with a commercial temperature grade. An analog switch is a semiconductor device that connects or isolates circuit nodes under digital control. The MAX14801CCM+ belongs to the analog switch family within the broader interface IC hierarchy, where multiplexers and switches route precision signals between sensors, amplifiers, converters, and test circuitry. Its low-charge-injection characteristic is especially relevant when switching analog signals whose timing accuracy or waveform integrity could otherwise be affected by injected charge. The verified product information identifies the MAX14801CCM+ as a 16-channel, high-voltage switch with low charge injection and a digital interface. Its HVCMOS implementation supports the high-voltage switching function described for the MAX14800-MAX14803 family. The device is intended primarily for ultrasonic imaging and printer applications, where multiple high-voltage analog channels must be selected using a serial or otherwise digital control mechanism. The 48-LQFP surface-mount package provides a compact solution for multi-channel analog routing while preserving individually accessible switch connections. Compared with mechanically selected high-voltage switches, the integrated digital control can simplify system sequencing and channel management. Exact voltage ratings, on-resistance, off leakage, bandwidth, channel capacitance, logic thresholds, and timing values must be confirmed in the manufacturer datasheet before final circuit design. Typical uses include ultrasonic receiver and transmitter signal paths, high-voltage printer-head interfaces, diagnostic acquisition equipment, and industrial test systems requiring 16 controlled switching points. In an ultrasonic system, the switch can route multiple channels while a digital controller establishes the required connection sequence and minimizes the burden of discrete control circuitry. The principal design consideration is ensuring that every driven logic pin and selected analog node stays within the device's verified voltage limits. Layout should preserve short analog traces, provide a stable ground reference, and prevent switching transients from coupling into sensitive neighboring nodes. Because the detailed electrical limits are not present in the supplied verified excerpts, designers should use the complete manufacturer datasheet for voltage, current, timing, and absolute-maximum-rating decisions. This product page consolidates verified distributor identification, family-level analog-switch characteristics, same-package alternatives, and application-oriented design guidance. It separates confirmed attributes from parameters that still require datasheet verification, helping engineers evaluate the MAX14801CCM+ without treating unverified numerical claims as design data.
MAX14802CCM+ - 16-Channel 48V High-Voltage SPST Switch | Analog Devices
The Analog Devices MAX14802CCM+ is a 16-channel, high-voltage SPST analog switching IC with 48 ohm on-resistance, a 2.7 V to 5.5 V logic supply, and a 48-pin TQFP package. Its 16 independent switches are controlled through a digital interface that clocks data into an internal 16-bit shift register and retains it in a programmable latch with enable control. An analog switch is an integrated semiconductor that routes signals between terminals under digital control. The MAX14802 belongs to the broader high-voltage switch IC hierarchy, where low charge injection, high off isolation, and controlled on-resistance are important for precision signal acquisition. Such devices sit between sensors, transducers, amplifiers, data converters, and external circuitry, allowing a controller to select and isolate measurement paths. The MAX14802 uses HVCMOS process technology to implement 16 high-voltage, low-charge-injection SPST switches. Its specified on-resistance is 48 ohm, while its single logic supply operates from 2.7 V to 5.5 V. The low charge injection characteristic is especially valuable when switching sensors whose output must remain accurate after each selection event. Each channel is represented by a bit in the internal 16-bit shift register. Serial data can therefore be shifted into the device while the retained switch states are controlled by the latch and enable logic. This architecture supports deterministic channel selection in systems that periodically scan transducers rather than requiring a separate control line for every channel. The device is intended for ultrasonic imaging and printer applications, where many high-voltage transducer connections must be multiplexed. It can also serve precision test systems, medical instrumentation, and industrial measurement equipment when the signal amplitude, injection behavior, and isolation requirements match the device ratings. Designers should verify the exact high-voltage operating limits, absolute maximum ratings, off leakage, switching time, and recommended output-drive conditions in the manufacturer datasheet before applying the device. PCB layout should provide a continuous ground reference, keep sensitive logic traces away from high-voltage switch nodes, and observe the 7 mm by 7 mm TQFP land-pattern requirements. This page combines verified manufacturer and distributor information, packaging details, engineering guidance, and the limitations of the available substitute data. It distinguishes a documented family candidate from fully confirmed drop-in replacements so procurement and design decisions are based on traceable evidence.
MAX14803CCM+ - 16-Channel High-Voltage Switch | Analog Devices
The Analog Devices MAX14803CCM+ is a 16-channel, high-voltage, low-charge-injection analog switching IC with 48-pin TQFP packaging. It provides 16 independent SPST switches, operates from a 2.7 V to 5.5 V supply, and has a specified on-resistance of 48 ohm. The device also provides 3500 ns switching times, 50 dB isolation performance, and operation from -40 °C to +85 °C. An analog switch is an integrated semiconductor device that routes analog signals between terminals under digital control. The MAX14803CCM+ belongs to the broader analog-switch hierarchy, where multiple SPST switches are controlled by a serial digital interface. Its 16-channel architecture reduces the number of control lines and PCB routing requirements compared with sixteen individually controlled discrete switches. The MAX14803CCM+ uses HVCMOS process technology to provide high-voltage switching in a low-charge-injection design. Data is clocked into an internal 16-bit shift register and retained by a programmable latch with enable and clear inputs. This architecture supports grouped switch-state management, making the device suitable for systems that need precise control over multiple high-voltage signal paths. Low charge injection helps limit unwanted voltage transients when a switch changes state. With a specified on-resistance of 48 ohm and switching times of 3500 ns for both turn-on and turn-off, the device favors controlled, repeatable switching over minimum propagation delay. The 50 dB isolation rating further supports applications requiring separation between controlled high-voltage paths. Typical uses include ultrasonic-imaging systems, printer electronics, and other industrial equipment that requires numerous high-voltage switching channels. The MAX14803 family is specifically identified for ultrasonic imaging and printer applications, while its serial shift-register control makes it appropriate for systems that can serialize switch commands from a controller or programmable logic device. PCB design should preserve the manufacturer's recommended supply decoupling and high-voltage clearances. Although the logic supply spans only 2.7 V to 5.5 V, the switched channels are intended for high-voltage signals, so creepage, clearance, insulation, and connector requirements must be evaluated for the actual operating voltage. The 48-pin TQFP package also requires thermal and assembly consideration at elevated ambient temperatures. This product page combines the verified manufacturer and distributor data with engineering-focused guidance on switching behavior, packaging, application fit, and verified alternatives. It distinguishes published specifications from unavailable details and avoids presenting unverified cross-brand substitutions as drop-in components.
MAX14805CCM+ - Low-Power RS-485 Transceiver | Maxim Integrated
The Maxim Integrated MAX14805CCM+ is a low-power RS-485/RS-422 interface transceiver intended for robust bidirectional communication over long cable runs and noisy industrial environments. The orderable CCM+ package supports surface-mount assembly, while its interface ratings, supply range, temperature range, and electrical limits must be confirmed against the current manufacturer datasheet before production release. The MAX14805 family is commonly considered for industrial data links, distributed control networks, building automation, and equipment-to-equipment communication where differential signaling improves noise immunity. An RS-485 transceiver is a physical-layer interface IC that combines a differential line driver with a differential receiver. It belongs to the hierarchy of transceiver IC, interface IC, communications IC, and semiconductor. Unlike a single-ended logic interface, an RS-485 interface uses differential voltage and a common-mode reference, allowing two devices to communicate over a balanced bus while rejecting much of the noise found between the signal and its return path. The related RS-422 standard primarily describes balanced point-to-point signaling, whereas RS-485 additionally supports multipoint bus arrangements. The key engineering characteristics to verify include supported data rate, transceiver operating mode, bus-driver and receiver electrical limits, supply voltage, shutdown behavior, propagation delay, and package pin configuration. These parameters determine whether the device can meet a specified protocol timing budget, cable-length target, or network topology. In particular, intended use of the MAX14805CCM+ in a half-duplex bus should be confirmed against its documented driver-enable and receiver-enable functions, as well as any bus-idle or fail-safe behavior. The MAX14805CCM+ should also be evaluated for signal integrity and system behavior rather than treated only as a logic-level part. Cable termination, biasing, grounding, connector pin assignment, and protection against electrostatic discharge can affect real-world reliability. The integrated transceiver provides the physical-layer conversion, but network integrity still depends on the external passive components and the topology of connected nodes. A qualified design should preserve the published common-mode range and avoid exceeding the absolute maximum ratings under transient conditions. Typical applications include industrial sensor and actuator networks, factory automation links, access-control equipment, instrumentation, building-control systems, and other isolated or distributed communications installations. In each case, the device can serve as the interface between a host controller with logic-level I/O and a balanced RS-485 or RS-422 physical layer. It may also be used in point-to-point RS-422 links when its electrical characteristics and pin functions satisfy that standard. Protocol handling remains the responsibility of a UART, microcontroller, transceiver controller, or other communications processor. A critical design step is to verify the exact MAX14805CCM+ pinout and exposed-pad or thermal requirements from the manufacturer datasheet before laying out a PCB. Place input and output decoupling capacitors close to their supply pins, route the differential pair as a tightly coupled pair, and provide a clear return-path strategy. Avoid long unprotected stubs, use only the termination scheme appropriate to the bus topology, and validate operation across cable length, data rate, temperature, and grounding conditions. This page provides a structured engineering framework for evaluating the MAX14805CCM+, including application suitability, unresolved datasheet parameters, commercial-data limitations, and verified drop-in-equivalent requirements. Because the supplied web search returned no component records or cross-reference results, missing electrical and mechanical values are explicitly marked rather than inferred, allowing engineers to distinguish confirmed product identity from data that still requires datasheet review.
MAX14805ECM+ - 16-Channel High-Voltage Switch | Maxim
The Maxim Integrated MAX14805ECM+ is a 16-channel, high-voltage analog switch IC with an 8:1, two-channel switch arrangement, supplied in a 48-LQFP 7 x 7 mm package. It uses two independent logic controls, DIN1 and DIN2, to operate two banks of eight SPST analog switches: DIN1 controls switch 0 through switch 7, while DIN2 controls switch 8 through switch 15. This architecture makes the device suitable for systems requiring numerous independently controlled high-voltage signal paths. An analog switch is an integrated semiconductor that routes an electrical signal between circuit nodes under digital control. In this product category, the MAX14805ECM+ belongs to the analog switch and switch matrix hierarchy, where multiple SPST switches are combined into a controlled routing network. Digital controls can place each switch into a conducting or nonconducting state, allowing one controller to manage external transducers, test points, or voltage domains without relying on separate mechanical relays. The verified product information identifies the MAX14805 as a high-voltage analog switch and confirms its 16-channel architecture. The two-bank organization is important because each eight-switch bank has a dedicated control input. MAX14805ECM+ is identified specifically as a 48-LQFP 7 x 7 mm device, while the related MAX14806 option adds 40 kΩ bleed resistors on every switch terminal. The MAX14805ECM+ is the appropriate selection when independent high-voltage switching is required without the MAX14806 bleed-resistor feature. The MAX14805 and MAX14806 family uses SPST switches rather than SPDT, DPDT, or multiplexer structures. This simplifies control logic but means that each switch provides only a connection path rather than selecting one of two destinations. System designers must therefore account for the off-state behavior, signal polarity, switch resistance, leakage, and control timing during PCB and firmware design. The related family is specified for an extended -40°C to +85°C temperature range according to the supplied datasheet information. Primary applications include ultrasound imaging systems, where multiple transducer-element connections must be switched during transmit and receive phases. The same 16-channel structure can also support industrial test systems, high-voltage instrumentation, medical signal-routing equipment, and multichannel measurement setups. In each case, the useful feature is coordinated control of many physical switching paths from two compact digital inputs. A critical design consideration is high-voltage layout safety. High-voltage traces must maintain the required clearance and creepage distances, while exposed package pads and test structures require appropriate insulation and guarding. Decoupling, control-logic levels, and the electrical limits of connected nodes must also be checked against the manufacturer datasheet before implementation. This product page consolidates verified distributor availability, package information, family architecture, and cross-reference findings into an engineering-oriented guide. It also separates confirmed facts from parameters that still require verification in the manufacturer datasheet, helping engineers evaluate the MAX14805ECM+ without confusing it with the resistor-equipped MAX14806 variant.
MAX14806CCM+ 16-Channel High-Voltage Analog Switch
The Analog Devices MAX14806CCM+ is a 16-channel high-voltage analog switch IC organized as two banks of eight SPST channels, housed in a 48-LQFP (7x7 mm) package. The device uses Maxim's 200V process technology for high-voltage switching and is controlled through a digital interface. The MAX14806CCM+ is designed for ultrasound imaging systems where receive-bank selection, probe multiplexing, and relay-equivalent signal routing are required. A high-voltage analog switch is a semiconductor device that routes analog signals under digital control while supporting voltage levels and isolation requirements that exceed ordinary low-voltage signal switches. In the signal-chain hierarchy, the MAX14806CCM+ is an interface IC and analog switch, with application-level roles in ultrasound probe selection, bank switching, and high-voltage signal isolation. The verified product information identifies sixteen high-voltage, low-charge-injection SPST switches, two independently controlled banks of eight channels, a digital control interface, and operation from -40°C to +85°C. These features make the device suitable for biplane and triplane ultrasonic probe arrangements, where multiple echo paths must be selected without changing the surrounding PCB layout. The low-charge-injection characteristic is particularly relevant when preserving small received ultrasound signals. The MAX14806CCM+ uses a 200V process technology, while the exact supported signal-voltage limits, on-resistance across all operating conditions, channel leakage, control-logic levels, and timing values require confirmation from the manufacturer datasheet. The package is identified by distributors as a 48-LQFP (7x7 mm), while the manufacturer describes the device as a 48-pin TQFP package. The same-source cross-reference states that the MAX14806CCM+ is a drop-in replacement for the Supertex HV2731. For ultrasound probe-bank selection, the device can replace mechanical or relay-based routing when the system requires digital control and low-charge-injection switching. In biplane imaging, two banks of eight channels can support the two probe banks. For triplane imaging, the switch can be integrated into a multiplexed receive architecture, subject to the detailed system timing and signal-integrity requirements. When designing the PCB, reserve the exact 48-pin LQFP footprint and route control signals away from sensitive analog inputs. Confirm the absolute maximum signal voltage, supply requirements, input capacitance, charge injection, off isolation, and power dissipation in the manufacturer datasheet before committing the design. This page combines verified manufacturer and distributor information, drop-in cross-reference data, application guidance, and explicit markers for parameters that were not supplied in the source data.
MAX1480ACPI+ - Isolated 250kbps RS-485/422 | Maxim
The Maxim Integrated MAX1480ACPI+ is a complete, electrically isolated RS-485/RS-422 data-communications transceiver with a 5 V supply and a maximum data rate of 250 kb/s. It is packaged in a 28-pin DIP and provides one-half transceiver operation for systems that require isolated differential data communication. An RS-485/RS-422 interface transceiver is an interface IC that converts logic-level signals into differential bus signals and receives those differential signals back into logic levels. The MAX1480ACPI+ belongs to the broader isolated interface IC and data-transceiver hierarchy, where electrical isolation separates the logic side from the communications bus. That isolation is useful when the transceiver must withstand ground-potential differences, reduce common-mode coupling, or protect sensitive equipment connected to a noisy industrial bus. Key features include complete electrically isolated RS-485/RS-422 interfacing, half-duplex operation, a 5 V operating supply, and a 250 kb/s data rate. The MAX1480A family is available in a 28-pin DIP package, making it appropriate for industrial-control, test-equipment, building-control, and isolated network-interface designs where through-hole construction and galvanic separation are important. The device integrates the driver, receiver, isolation barrier, and associated interface functions into a hybrid microcircuit. A single 5 V supply on the logic side powers both sides of the interface according to the manufacturer description. This integrated approach reduces the number of external isolation components and simplifies the physical implementation of an isolated serial-data port. Typical uses include automated test equipment, HVAC and building-control networks, industrial-control links, local-area networks, and EMI-sensitive isolated RS-485 or RS-422 interfaces. The 28-pin DIP format is useful where a leaded package is preferred for manual assembly, repair, or compatibility with an existing through-hole board. Designers should verify the complete pinout, isolation ratings, bus loading, termination, and transient protection against the manufacturer datasheet before laying out a new PCB. Because this is a through-hole DIP device, connector creepage, isolation-barrier placement, and cable-side surge protection require particular attention. This page combines verified distributor information, manufacturer-family details, same-package alternatives, comparison parameters, and practical design guidance to support component selection beyond a basic distributor listing.
