MAX485CPA+

MAX485CPA+ - Low-Power RS-485/RS-422 Transceiver | Analog Devices

The Analog Devices MAX485CPA+ is a low-power, slew-rate-limited RS-485/RS-422 interface transceiver with one driver and one receiver in an 8-pin PDIP package. The verified product data identifies it as a half-duplex transceiver designed for RS-485 and RS-422 communication, supporting low-power differential bus communication where controlled edge rates help reduce unwanted reflections and electromagnetic interference. The MAX485CPA+ is suitable for industrial equipment, instrumentation, data acquisition, building controls, and other systems that require robust differential signaling over longer cable runs. An RS-485/RS-422 transceiver is an interface IC that converts logic-level digital signals into differential bus signals and receives differential signals back from the bus. In this product family, the transceiver combines a transmitter and receiver while supporting half-duplex communication, meaning the shared bus can transmit or receive according to the system design. The MAX485CPA+ belongs to the broader interface-IC and RS-485 transceiver hierarchy, linking digital logic equipment to a physical differential communication network. Key verified features include a low-power communication architecture, slew-rate-limited signaling, one driver, one receiver, and compatibility with both RS-485 and RS-422 applications. The verified distributor listings identify the package as an 8-pin PDIP and categorize the part as a half-duplex transceiver. The eight-pin package supports through-hole assembly and provides the standard transceiver connections needed for a board-level industrial interface. The official Analog Devices product page describes the MAX485 family as low-power transceivers for RS-485 and RS-422 communication. The transceiver architecture is important in systems where a controller UART connects to a field bus. The driver presents the outgoing data as a differential signal, while the receiver converts the differential bus state into a logic-level signal for the host. Slew-rate limiting reduces the high-frequency content of transitions, helping control signal integrity on terminated or moderately loaded buses. Designers must still select the correct cable, termination, grounding, and biasing strategy for the installed network. Typical applications include industrial automation links, remote sensor networks, security equipment, test and measurement systems, building automation controllers, and communication links between embedded processors and external transceivers. A microcontroller or programmable controller can use the MAX485CPA+ to communicate over a longer differential bus instead of relying on a single-ended signal. The design must account for bus direction control, driver enable timing, receiver enable timing, and the electrical limits of the connected network. For PCB design, place the transceiver close to the connector and route the differential pair with consistent geometry, minimal stubs, and appropriate grounding. Use termination only where required by the bus topology, and verify the cable length, baud rate, node count, and common-mode environment. This page combines verified product descriptions, distributor sourcing information, cross-reference results, and practical interface guidance for engineers evaluating the MAX485CPA+.

MAX485CSA+

MAX485CSA+ - 2.5Mbps RS-485/RS-422 Transceiver | Analog Devices

Analog Devices MAX485CSA+ is a low-power half-duplex RS-485 and RS-422 transceiver with one driver and one receiver, a maximum data rate of 2.5Mbps, and an 8-pin SOIC package. It is designed for bidirectional serial-data links where a compact interface IC must support both differential transmission and differential reception. Unlike a receiver-only line driver or a transmitter-only RS-485 device, the MAX485CSA+ combines both functions and supports half-duplex communication by coordinating its driver and receiver through DE and /RE control inputs. An RS-485 transceiver is a communications interface IC that converts logic-level signals into differential bus voltages and reconstructs logic data from a differential bus. Within the broader hierarchy, the MAX485CSA+ is an RS-485/RS-422 interface transceiver, also described as a line transceiver or differential communications transceiver. It supports balanced signaling systems intended for longer interconnects and noise-immune industrial communication compared with single-ended logic interfaces. The verified manufacturer description identifies the MAX485 family as low-power transceivers for RS-485 and RS-422 communication. Each device contains one driver and one receiver. The MAX485 driver does not impose slew-rate limiting, allowing the family to transmit at data rates up to 2.5Mbps. The verified distributor listing identifies MAX485CSA+ as a 1/1 half-duplex transceiver in an 8-SOIC package. Typical uses include industrial automation links, building-control networks, instrumentation buses, and other balanced serial-data systems. In a half-duplex design, the system controller enables the driver during transmission and enables the receiver during reception. Because the driver and receiver share the same differential bus pins, the DE and /RE signals should be controlled so that the transmitter is disabled while receiving when echo-free reception is required. A principal design consideration is the unreferenced or referenced bus topology. The MAX485CSA+ supports a multidrop communications arrangement, but cable length, data rate, termination, biasing, and transceiver enable sequencing must be evaluated together. The differential bus should use twisted-pair wiring, with termination placed only at the physical ends of the cable and common-mode biasing provided by the system where required. This page consolidates the verified manufacturer description, distributor package and ordering information, a published starting price of $0.0788 as of 2026-10-28, and web-supported drop-in alternatives. It also identifies temperature-grade and qualification data that require confirmation before production release.

MAX485CSA+T

MAX485CSA+T - 2.5Mbps RS-485 Transceiver | Maxim Integrated

Maxim Integrated MAX485CSA+T is a low-power, half-duplex RS-485 and RS-422 interface transceiver with one driver and one receiver, a maximum data rate of 2.5Mbps, a 4.75V to 5.25V supply range, and an 8-pin SOIC package. It converts logic-level signals into balanced differential bus signals and receives differential bus data back into a logic-level output, allowing reliable communication over longer cable runs than single-ended interfaces. An RS-485 transceiver is a physical-layer interface IC used to connect processors, controllers, meters, sensors, and industrial equipment to a differential communication bus. The MAX485 family supports half-duplex operation because its single driver and receiver share the same bus pins. RS-422 and RS-485 use differential signaling, common-mode rejection, and galvanically isolated cable pairs to reduce sensitivity to noise and ground-potential differences. The MAX485CSA+T operates from a single 4.75V to 5.25V supply and supports data rates up to 2.5Mbps. Its driver includes short-circuit current limiting and thermal protection, while the receiver provides fail-safe behavior for certain bus conditions. The commercial-temperature version is specified for operation from 0°C to 70°C. The SOIC-8 package supports compact, surface-mount PCB layouts, and the +T ordering suffix identifies the tape-and-reel shipping configuration. Technically, the device uses separate active-low receiver-enable and driver-enable control inputs, allowing the driver and receiver to be controlled independently when required. A logic-high DE input activates the transmitter, while a logic-low /RE input enables the receiver. The receiver output provides a usable signal when the bus is idle, helping a system distinguish an inactive network from a valid data state. Component values around the interface should be selected from the bus topology and termination requirements rather than added arbitrarily. Typical applications include industrial RS-485 links between supervisory controllers and remote sensors, building-automation equipment, security and access-control panels, industrial motor controllers, instrumentation links, and embedded data-acquisition systems. The 2.5Mbps capability is suitable for short, high-speed bus segments, while longer installations should use lower data rates to maintain reliable rise-time and signal-integrity performance. The primary layout consideration is the bus network itself. Place termination resistors only at the two physical ends of the bus, use twisted-pair wiring, route the differential pair as a tightly coupled pair, and keep the transceiver close to the connector to minimize reflections and radiated noise. Confirm the logic levels, grounding strategy, cable length, node count, and grounding configuration before releasing a production design. This product overview combines the manufacturer interface description with practical guidance for implementing a robust RS-485 network. It also identifies pin-compatible alternatives, application-level usage, PCB considerations, and the key electrical parameters engineers should review when replacing or sourcing the MAX485CSA+T.

MAX485CUA+

MAX485CUA+ - 5V RS-485/RS-422 Transceiver, 2.5Mbps | ADI/Maxim

The Analog Devices (formerly Maxim Integrated) MAX485CUA+ is a low-power transceiver for RS-485 and RS-422 communication, integrating one driver and one receiver in an 8-pin uMAX/uSOP package. It operates from a single 4.75V to 5.25V supply, supports data rates up to 2.5Mbps with no slew-rate limiting, and delivers typical supply current of 300 uA under quiescent or full-duplex load conditions. An RS-485/RS-422 transceiver is a bus-interface IC that converts between single-ended UART/CMOS logic on the controller side and the differential voltage signaling required for robust long-distance, multi-drop communication over twisted-pair cable. Transceivers such as the MAX485CUA+ sit inside the broader Interface IC family and provide the physical-layer (PHY) bridge for industrial fieldbus networks including Modbus, Profibus DP, DMX512, and BACnet, where common-mode noise immunity and cable lengths up to 1200 m are required. Key features of the MAX485CUA+ include 2.5Mbps maximum data rate, 1/8 unit-load (up to 256 transceivers on a bus), thermal-shutdown protection, short-circuit current limiting on the driver outputs, a low-current shutdown mode (on the MAX481/MAX483/MAX487 variants, not the MAX485 itself), true fail-safe receiver inputs that guarantee a logic-high output when the differential input is open or shorted, and an ESD rating of greater than 15 kV HBM on the bus pins per the MAX485 datasheet family. Architecturally, the MAX485CUA+ uses a differential line driver with slew-rate-limited edges on slower speed grades and an un-limited edge rate here for maximum 2.5Mbps throughput, paired with a differential receiver with internal hysteresis for noise rejection. The wide 4.75V to 5.25V supply range is compatible with 5V TTL logic rails; a 3.3V variant (MAX3485) and isolated versions (MAX1480) exist in the same family for different system-level needs. Typical applications include industrial multi-drop RS-485 networks, building-automation HVAC controllers, point-of-sale terminals, packet-based utility metering, and any embedded system that requires half-duplex differential communication over long cables in electrically noisy environments. When designing with the MAX485CUA+, place a 100 ohm termination resistor at each end of the bus and use a low-ESR 100 nF decoupling capacitor as close to VCC as possible. Select 100 ohm twisted-pair cable (EIA-485 characteristic impedance) and avoid star topologies; daisy-chain is required to prevent reflections.

MAX485ECPA+

MAX485ECPA+ - 1 Mbps RS-485/RS-422 Half-Duplex Transceiver | Maxim

The Maxim Integrated MAX485ECPA+ is a single-driver, single-receiver half-duplex RS-485/RS-422 transceiver with low-power operation, slew-rate-limited (limited EMI) driver outputs and ±15 kV ESD protection on every driver output and receiver input, packaged in an 8-pin PDIP (through-hole) DIP-8 package. Key headline parameters are a 5 V single supply (4.5 V to 5.5 V), a 1 Mbps data rate from the limited-slew-rate driver, and ±15 kV ESD ruggedization; the device is a 1/1 transceiver in an 8-pin PDIP-8 package. An RS-485 transceiver is a differential line-interface IC inside the broader hierarchy of interface ICs -> differential line driver/receiver -> communications transceiver -> semiconductor. It converts a logic-level serial signal (DI) into a balanced differential pair on the A and B bus wires, and converts a differential bus voltage back into a logic-level receiver output (RO). Unlike a single-ended RS-232 transceiver, an RS-485 driver drives a balanced, floating differential pair, so common-mode noise is rejected and cables up to about 1200 metres at low data rates can be supported. Key features of the MAX485ECPA+ include a limited-slew-rate driver that minimizes EMI and ground bounce on the bus, allowing operation without external slew-control resistors; short-circuit current limiting on the driver outputs; thermal shutdown for excessive power dissipation; and a low quiescent current design that supports low-power node designs. A shutdown (sleep) input is not present on this device, so the node stays enabled while powered, which simplifies bus management in fixed installations. Technically, the MAX485ECPA+ is a single-channel half-duplink device: DE (driver enable) and /RE (receiver enable) are separate pins, so a design can transmit, receive, or disable the bus independently for fail-safe biasing. The driver is designed for a balanced network so that no additional termination or bias resistors are required on the driver side, although the bus must still be properly terminated at the two physical ends and biased at exactly one point if the transceiver's receiver thresholds require it. Typical applications include industrial RS-485 multidrop buses, building automation and HVAC controllers, energy meters, inverters and solar trackers, security and access-control panels, and instrumentation links to remote sensors. The 8-pin PDIP package is preferred for leaded industrial equipment where through-hole assembly, hand soldering, and field replacement are required. The main design consideration is ESD and surge coupling: although the internal protection is rated at ±15 kV on the bus pins, the ESD paths are only effective if the bus entry point is close to the transceiver, so a multi-layer board with a solid ground plane and short A/B traces is strongly preferred over a long unprotected stub. This page consolidates distributor pricing, verified package and interface details, pin-compatible drop-in alternatives in the same PDIP-8 footprint, and practical RS-485 layout and termination guidance that are not collated on a single manufacturer page.

MAX485ECSA+

MAX485ECSA+ - 2.5 Mbps RS-485 Transceiver | Analog Devices

The Analog Devices MAX485ECSA+ is a low-power RS-485 and RS-422 half-duplex line transceiver packaged in an 8-pin SOIC, operating at up to 2.5 Mbps with 15 kV ESD protection on driver outputs and receiver inputs. It combines one driver and one receiver in a package designed for noisy industrial communication links. According to the manufacturer data summarized by distributor listings, the MAX485E family is intended for low-power RS-485 and RS-422 communications in harsh environments. A half-duplex transceiver is a network interface that transmits and receives data on the same differential bus pair but cannot do both simultaneously. The MAX485ECSA+ supports a multidifferential bus architecture using differential data lines for noise immunity, while its driver and receiver enable inputs allow the host to control bus direction. This device sits within the hierarchy of line transceiver, physical-layer interface IC, communication interface, and semiconductor. Principal features include a maximum data rate of 2.5 Mbps, 15 kV ESD protection, slew-rate-limited driver outputs, and low-power operation. The E version differs from the standard MAX485C family by emphasizing electrostatic-discharge protection for industrial environments. The narrow SOIC-8 package also supports compact PCB layouts in distributed control, building automation, instrumentation, and industrial data-acquisition systems. The transceiver uses separate active-low receiver-enable and driver-enable control inputs, permitting a connected MCU to assert the driver for transmission and release it during reception. Differential signaling improves common-mode noise rejection on long cables, but system performance still depends on correct bus termination, controlled cable characteristics, protective grounding, and an appropriate transceiver slew rate. The receiver converts the A and B differential voltage into a single-ended logic signal at the R pin. Typical uses include industrial supervisory control, factory automation, building automation, security equipment, remote instrumentation, and RS-485 links between microcontrollers or programmable logic controllers. The MAX485ECSA+ is particularly appropriate when ESD exposure is more important than minimizing package size. For low-data-rate meter buses, lower-power or higher-node-count variants may be preferable, so protocol and bus-topology requirements should be confirmed before substitution. The critical design consideration is bus configuration. Place termination resistors of 120 ohm at both physical ends of a standard RS-485 trunk, not at every node, and avoid star topologies with heavy loading. Use a common reference ground, controlled cable routing, and suitable surge protection for cables leaving an enclosure. The MAX485ECSA+ is a line transceiver, not a full RS-232 interface, so the host must use differential-bus-compatible logic and a suitable isolation strategy where required. This page consolidates verified distributor availability, an identified pin-compatible cross-reference, package-level comparison data, and application-specific engineering guidance. It distinguishes the MAX485ECSA+ from related MAX485 variants based on verified package, data-rate, ESD-protection, and interface information rather than treating all similarly named transceivers as interchangeable.

Its slew-rate-limited driver is designed for reliable, low-power communication over noisy industrial, commercial, and instrumentation networks. An RS-485 transceiver is an interface IC that combines differential line-driver and receiver functions into one package. RS-485 supports balanced, multipoint communication over longer distances than a single-ended interface, while RS-422 provides a compatible differential signaling environment. The MAX485 family belongs to the broader transceiver, interface IC, and semiconductor hierarchy used to connect controllers, sensors, meters, and industrial equipment. The device combines low-power operation with a slew-rate-limited output, ±15kV electrostatic-discharge protection on its driver outputs and receiver inputs, and separate receiver-enable and driver-enable controls. These characteristics suit distributed systems where cable transients and reflected signals are possible. Its 4.75V to 5.25V operating supply supports conventional 5V communications equipment, while the 8-pin SOIC package simplifies assembly into industrial-control and data-acquisition products. Each MAX485ECSA-T contains one driver and one receiver. The receiver can remain active while the driver transmits, allowing full-duplex behavior when two appropriately connected transceivers are used. The driver’s controlled slew rate limits high-frequency harmonic content, although the maximum signaling rate and propagation-delay figures should be confirmed against the manufacturer’s electrical-characteristics table for the selected operating conditions. Typical applications include industrial sensor buses, building-automation controllers, utility metering, laboratory instrumentation, and factory data-acquisition links. The same-package pin arrangement can also support PCB reuse when a qualified alternative has equivalent electrical ratings and protocol behavior. Differential routing, proper grounding, termination, and protection-network design remain essential in long or noisy cable installations. Design the bus around the driver’s current capability, receiver sensitivity, and the maximum data rate permitted by the total cable length and topology. Keep the transceiver and protection components close together, route the differential pair as a tightly coupled pair, and avoid placing sensitive analog signals parallel to the communications conductors. This product page combines exact orderable-part information, structured electrical characteristics, pin-compatible replacement options, a parameter comparison, and practical PCB guidance. It helps engineers assess the MAX485ECSA-T as a 5V, ESD-protected half-duplex interface solution for industrial and commercial RS-485/RS-422 links.

MAX485EEPA+ - 15kV ESD RS-485 Transceiver | Maxim Integrated

The Maxim Integrated MAX485EEPA+ is a low-power, slew-rate-limited half-duplex RS-485 and RS-422 transceiver with one driver and one receiver, 15 kV ESD protection, and a 4.75 V to 5.25 V supply in an 8-pin PDIP package. It is designed for bidirectional industrial and instrumentation data links where reduced transition rates, overload protection, and reliable differential signaling are important. An RS-485/RS-422 transceiver is an interface IC that converts logic-level signals to and from differential bus voltages. It belongs to the transceiver hierarchy: interface IC -> RS-485/RS-422 transceiver -> differential communication interface. The MAX485EEPA+ combines a transmitter, receiver, driver-enable control, receiver-enable control, and bus pins in one device, reducing the component count required for a bidirectional serial-data link. The MAX485EEPA+ provides one transmit channel and one receive channel. Its 15 kV ESD protection is the principal rugged-environment feature identified in the supplied manufacturer-related data. Slew-rate limiting helps control edge speed and reduce reflected-signal and electromagnetic-interference problems on longer cables. The low-power operating mode also makes the device suitable for equipment where the transceiver remains connected to a bus even when communication is inactive. Communication is established by connecting the differential A and B pins to the twisted-pair bus. The DE input enables the driver, while the active-low RE input enables the receiver. These controls allow the two halves of the transceiver to be disabled independently, supporting point-to-point links, multidrop RS-485 networks, and panel-mounted equipment where a local test loop can be useful. Logic-side signals connect to DI for transmit data and RO for received data. Typical uses include industrial sensor gateways, programmable logic controller interfaces, building-automation equipment, industrial test instruments, and RS-422 links between equipment cabinets. The 5 V supply matches systems that already operate from regulated 5 V rails. Because the device is half-duplex, software or hardware must control bus direction and avoid transmission conflicts when several nodes share the same pair. For reliable operation, route the A and B differential pair as a tightly coupled twisted pair, minimize stub branches, and place termination at physical ends of the bus rather than at every node. Provide local supply decoupling and verify that transceiver-enable timing prevents two drivers from driving the bus simultaneously. Unverified transceiver thresholds, current limits, and exact timing values must be confirmed in the manufacturer datasheet before final release. This product page combines verified distributor descriptions, cross-reference evidence, package and pinout information, replacement guidance, and practical bus-layout considerations. It also distinguishes documented drop-in family options from alternatives that would require a different PCB footprint.

It integrates one driver and one receiver, supports data rates up to 2.5 Mbps, and operates from a single 5V supply drawing 1 mA (typical) quiescent current while allowing up to 32 transceivers on the bus. The slew-rate-limited driver minimizes EMI and reflections on improperly terminated cables, enabling error-free transmission over twisted-pair media up to 1200 m. The MAX485EESA+ includes ±15kV HBM ESD protection on the driver output and receiver input pins, making it suitable for hot-swap and field-bus installations where cable discharge events are common. An RS-485/RS-422 transceiver is a differential line driver/receiver IC that converts a single-ended TTL/CMOS logic signal into a balanced differential pair suitable for transmission over twisted-pair cabling. RS-485 supports multi-drop (up to 32 unit loads, 256 with newer parts) half-duplex communication across long distances; RS-422 is a point-to-point full-duplex standard. The MAX485EESA+ belongs to the half-duplex RS-485 transceiver class within the larger interface-IC category of wired communication semiconductors. Key features include ±15kV HBM ESD protection, slew-rate-limited driver for low EMI, 1/2 unit-load input impedance, thermal-shutdown protection, and short-circuit current limiting. The receiver provides fail-safe operation, guaranteeing a logic-high output when the bus inputs are open, shorted, or idle, eliminating the need for external biasing resistors at the ends of the cable. Current limiting and thermal shutdown protect the driver outputs against excessive power dissipation caused by bus contention or output short circuits to ground or supply. Typical applications include industrial field-bus networks (Modbus, Profibus, DMX512), building automation (BACnet, LonWorks), HVAC controls, security systems (access control, alarm panels), and point-of-sale (POS) equipment. The wide operating temperature range (-40 °C to +85 °C for the E grade) and rugged ESD rating make it a drop-in solution for industrial controllers, PLCs, and motor-drive interfaces. When designing with this device, place 100 nF bypass capacitors as close as possible to VCC (pin 8) and provide a 120 Ω termination resistor at each end of the bus when using the highest data rates. Keep the PCB stub length to the connector below one-tenth of the driver rise time to minimize reflection-induced jitter. Use twisted-pair cable with 100 Ω characteristic impedance (e.g., Belden 3106A) and avoid running RS-485 traces parallel to noisy switching rails.

A transceiver IC combines a differential line driver and receiver on one die, allowing a digital UART signal to travel over a balanced, noise-resistant bus. The MAX485 family belongs to the interface IC hierarchy: RS-485 transceiver → differential transceiver → wired-communication interface IC → semiconductor. Its half-duplex architecture supports bidirectional communication by sharing one differential pair and changing direction through the driver-enable and receiver-enable controls. The MAX485EESA+T combines a 4.75 V to 5.25 V supply range with a 2.5 Mbps maximum data rate. Its slew-rate-limited driver reduces unwanted high-frequency energy on the bus, while ±15 kV ESD protection strengthens the interface against electrostatic discharge encountered in industrial environments. The low-power design also supports systems where the transceiver must remain connected to a 5 V control rail. Operationally, the device provides separate receive-enable and driver-enable inputs, allowing the receiver to remain active while transmission is disabled. The receiver converts differential bus voltage into a logic-level output, while the driver converts a logic-level input into differential A and B outputs. This arrangement supports both point-to-point links and multi-drop RS-485 networks when termination and biasing are designed correctly. Typical applications include industrial control networks, building automation, instrumentation links, data acquisition systems, motor controllers, and factory communication equipment. The MAX485EESA+T is especially appropriate for factory environments where ESD exposure, long cable runs, and grounded or ungrounded equipment can create substantial bus-level transients. PCB design should preserve the pinout and provide the decoupling, protection, and termination required by the bus. Place the VCC bypass capacitor close to the supply pin, route the differential pair as a balanced pair, and use a protection network designed for the expected surge and ESD environment. Avoid long unprotected stubs because they can create impedance discontinuities and reflections. This product page combines the manufacturer-datasheet specifications, verified package and cross-reference information, drop-in alternatives, and application-focused engineering guidance.

It is designed for industrial, instrumentation, and distributed-control links that require reliable differential data transmission over longer cable runs. The verified listing identifies the device as a half-duplex RS-422/RS-485 transceiver with a 4.75 V to 5.25 V supply range. An RS-485/RS-422 transceiver is an interface IC that converts logic-level digital signals into differential bus signals and converts received differential signals back into CMOS-compatible logic. RS-422 and RS-485 use differential signaling to improve noise immunity and allow communication across cables in electrically noisy environments. The MAX485EPA+ supports one driver and one receiver, making it suitable for point-to-point, multidrop, and half-duplex bus arrangements when the system includes the required enable control, termination, biasing, and transceiver-direction logic. The MAX485EPA+ is specified as a low-power transceiver with driver short-circuit current limiting and protection. The verified product data states that the output slew rate is not limited and that the device can transmit up to 2.5 Mbps. This speed capability makes it useful for factory automation, industrial control, building automation, and embedded communications where the bus must carry bursts of digital data while maintaining a compact, widely available 8-pin through-hole package. The device is suitable for RS-485 networks connected to microcontrollers, sensors, motor controllers, data converters, and remote I/O modules. The system designer must account for bus topology, cable length, termination resistors, common-mode limits, grounding, and the direction-control interface. The MAX485EPA+ does not by itself provide galvanic isolation; applications requiring isolation between high-energy bus wiring and control electronics should add suitable isolation components and protection devices. Because the MAX485EPA+ uses a PDIP package, it is particularly useful for prototypes, serviceable equipment, and industrial products assembled through-hole rather than high-density automated surface-mount processes. The 8-pin package simplifies inspection and rework. The plus suffix identifies the leaded product ordering code shown in the verified distributor records; package, temperature, and qualification requirements should still be checked against the exact manufacturer ordering information before production release. This page combines verified distributor listings, manufacturer-family information, pricing context, and practical interface design guidance. It is intended to help engineers identify whether the MAX485EPA+ fits an existing RS-485 or RS-422 PCB and to distinguish it from alternatives with different package, speed, supply, or protection characteristics.

MAX485ESA+ - 5V RS-485/RS-422 Transceiver, 2.5Mbps, SOIC-8

The Analog Devices (formerly Maxim Integrated) MAX485ESA+ is a low-power, slew-rate-limited RS-485/RS-422 transceiver housed in an 8-pin SOIC package. The device contains one driver and one receiver, operates from a single 5 V supply, and supports data rates up to 2.5 Mbps with half-duplex communication. It draws between 120 µA and 500 µA of supply current when unloaded or fully loaded with disabled drivers, making it well suited for power-sensitive industrial networks. What is an RS-485/RS-422 transceiver? An RS-485 transceiver (TIA/EIA-485) is a differential line driver/receiver IC that converts a single-ended TTL/CMOS logic signal into a balanced differential signal suitable for transmission over twisted-pair cabling. RS-485 transceivers belong to the broader physical-layer IC family inside Interface ICs, which also includes RS-232, CAN, and I2C transceivers. The half-duplex variant shares one differential pair between driver and receiver, reducing cable cost for bidirectional buses such as Profibus, Modbus RTU, and DMX512. Key features of the MAX485ESA+ include a 1/8 unit-load input impedance (allowing up to 256 transceivers on a single bus), driver short-circuit current limiting, and thermal-shutdown protection that places the driver outputs into a high-impedance state. The receiver includes a fail-safe function that guarantees a logic-high output when the differential input is floating, shorted, or terminated but idle. Industry-standard SOIC-8 pinout and 5 V operation make the part a drop-in upgrade or replacement for legacy Maxim/Intersil RS-485 designs. Internally, the driver uses a slew-rate-limited output stage to reduce EMI and reflections on unterminated cables, while the receiver incorporates hysteresis and an input filter to reject common-mode noise. The common-mode input voltage range extends from -7 V to +12 V relative to ground, supporting long cable runs with significant ground potential differences between nodes. Typical applications include industrial field-bus networks (Modbus, Profibus, BACnet), building automation, HVAC controllers, motor-control command links, point-of-sale terminals, and multidrop RS-485 utility metering. Designers select the MAX485ESA+ when they need a proven, second-source-friendly 5 V half-duplex transceiver with long-term availability. When designing with this part, place 120 Ω termination resistors only at the two physical ends of the bus to avoid loading the drivers. Use a 100 nF decoupling capacitor placed within 5 mm of the VCC pin, and route the A/B differential traces with controlled 100 Ω differential impedance and ground-referenced return paths. This page synthesizes distributor pricing, drop-in compatible alternatives (including the SN75176B and SP485EN-L/TR families), and practical design notes that go beyond the bare datasheet, helping engineers select and source the right transceiver faster.

MAX485ESA+T

MAX485ESA+T - 2.5Mbps RS-485/RS-422 Transceiver | ADI

Analog Devices MAX485ESA+T is a low-power half-duplex RS-485/RS-422 interface transceiver with one driver and one receiver, a maximum data rate of 2.5Mbps, and a 4.75V to 5.25V supply range. The device is supplied in an 8-pin SOIC package and is intended for industrial bidirectional serial-data links. An RS-485 transceiver is an interface IC that combines a differential line driver and differential receiver. These transceivers connect a host controller, PLC, sensor, or industrial endpoint to a balanced communication bus. The RS-485 standard hierarchy supports longer, noise-resistant interconnects than single-ended interfaces, while RS-422 compatibility allows the same device family to serve point-to-point links. Driver enable and receiver-enable inputs provide local control over bus direction and reception. The MAX485ESA+T uses a 4.75V to 5.25V supply and supports data rates up to 2.5Mbps. Its driver is short-circuit-current limited and protected, an important feature when a bus fault drives a line into a low-impedance condition. The integrated receiver converts differential bus voltage into a logic-level output, while the driver converts logic-level data into differential output. This combination supports half-duplex operation, in which the same pair of conductors carries transmitted and received data at different times. The 8-pin SOIC package keeps the implementation compact and familiar to industrial-control board designers. Because the MAX485ESA+T does not limit its slew rate, it can transmit at up to 2.5Mbps according to the provided manufacturer and distributor documentation. That speed is useful for factory automation, instrumentation, and embedded control networks, although cable length, termination, topology, and signal integrity become increasingly restrictive as data rate rises. Typical uses include RS-485 fieldbus connections, motor-control diagnostics, industrial sensor gateways, building-control equipment, and communications between a microcontroller and remote peripheral. In a typical circuit, the transceiver sits between a UART-capable controller and a protected, twisted-pair bus. A termination resistor is placed at each end of the bus, while common-mode protection and chassis-grounding practices may be needed in electrically noisy installations. Designers should verify that the selected cable length and topology can support the intended 2.5Mbps rate, connect the receiver and driver enables for the required half-duplex behavior, and maintain compatible logic levels across the system. The 5V supply requirement also requires a 4.75V to 5.25V regulator rather than a 3.3V rail. This page combines the verified manufacturer and distributor information with package-level engineering guidance, practical interface considerations, pricing context, and pin-compatible replacement analysis to support faster component selection and PCB migration.

MAX485MJA

MAX485MJA - 2.5 Mb/s RS-485/RS-422 Transceiver, 8-CERDIP | Analog Devices

The Analog Devices MAX485MJA is a 1/1 half-duplex RS-485/RS-422 interface transceiver rated for 2.5 Mb/s data rate, packaged in an 8-pin CERDIP military-grade ceramic dual-inline package. Each device contains one driver and one receiver, providing a complete differential bus interface on a single die. An RS-485 transceiver is the physical-layer bridge between a logic-level UART or microcontroller and a balanced, multi-drop cable bus. RS-485 belongs to the differential signaling family of interface ICs, sitting between the transceiver category and the wider Interface ICs > Drivers/Receivers/Transceivers hierarchy. Because differential signaling sends a signal and its complement over a twisted pair, it rejects common-mode noise, allows long cable runs, and supports multiple nodes on one bus, making it the de facto standard for industrial automation, building controls and instrumentation networks. Key features of the MAX485MJA include a low-power slew-rate-limited driver that reduces EMI and ringing on slow edges, one driver and one receiver per package, and a 2.5 Mb/s data rate as listed by distributors for the MAX485 series. The /RE and DE pins give the designer independent control over driver enable and receiver enable, allowing half-duplex bus turnaround control from a single microcontroller pin. Operating over the extended industrial temperature range, the CERDIP-8 mechanical format gives long-term availability for rugged and legacy industrial platforms. The device implements a classic current-mode differential driver with a failsafe bias network so that an unpowered or disconnected node does not clamp the bus, plus a fail-safe receiver stage that interprets an open or shorted bus as a defined logic state. The 8-pin pinout (RO, /RE, DE, DI, GND, A, B, VCC) is shared across the entire MAX48x family, which simplifies cross-referencing and second sourcing across ceramic, plastic and surface-mount variants. Typical applications include industrial RS-485 field buses such as Modbus RTU networks, building HVAC and lighting controllers, PLC and data-acquisition module interfaces, POS terminals and industrial instrumentation, and retrofit of legacy 2.5 Mb/s RS-485 equipment where a ceramic military-temperature package is required. When designing with the MAX485MJA, note that the 8-pin package leaves no dedicated fail-safe bias resistor footprint; many designs add 100 ohm to 220 ohm termination resistors and a fail-safe bias network externally. Because the CERDIP-8 body is larger than a standard PDIP-8, check board mechanicals and pin-hole spacing, and keep the A and B differential pair away from switching nodes and high-current returns to preserve common-mode margin. This page consolidates verified distributor pricing, a drop-in cross-reference set, pin-level detail and applied design guidance that is not available from a single manufacturer datasheet, helping engineers qualify this part quickly for both new and legacy industrial designs.

The Analog Devices MAX487ESA+ is a low-power, slew-rate-limited RS-485/RS-422 transceiver containing one driver and one receiver in an 8-pin SOIC (NS) package. It operates from a single 5V supply, supports data rates up to 250 kbps, and provides ±15 kV ESD protection on driver output and receiver input pins. The MAX487ESA+ features low quiescent supply current (120 µA to 500 µA) under load and 0.1 µA in shutdown, making it ideal for power-sensitive multi-drop networks. An RS-485 transceiver is a differential line driver/receiver that translates logic-level UART signals to a robust differential signal capable of being transmitted over long cables in electrically noisy environments. RS-485 supports multi-drop configurations of up to 32 transceivers on a single twisted pair, enabling half-duplex or full-duplex communication over distances up to 1200 m. RS-485 transceivers belong to the broader interface IC category within power management and communication ICs, and are standardized under TIA-485 (formerly EIA-485). Key features include slew-rate-limited driver outputs that reduce EMI and reflections on unterminated or improperly terminated cables, true fail-safe receiver inputs that guarantee a known output state when the bus is idle or shorted, and a low-current shutdown mode that places the device in <0.1 µA quiescent for power-saving operation. The MAX487ESA+ carries ±15 kV HBM ESD protection on the bus pins, providing robust tolerance to electrostatic discharge events during handling and field installation. The MAX487ESA+ integrates a complete half-duplex RS-485 link layer with internal cable termination management through slew-rate control rather than discrete termination. Its 5V single-supply operation simplifies power architecture in industrial 24V-rail-derived systems, and its robust differential signaling supports industrial control, building automation, and point-of-sale applications. Typical applications include industrial fieldbus networks (Modbus, Profibus), HVAC building automation systems, motor control encoder feedback, point-of-sale (POS) terminals, security system intercom panels, and remote utility metering. The MAX487ESA+ pinout and protocol match the broader MAX481/MAX483/MAX485/MAX487/MAX1487 family, allowing drop-in upgrades and obsolescence mitigation across existing designs. Design considerations: include a 100 nF decoupling capacitor close to VCC, place a 120 Ω termination resistor across the differential pair only at the cable ends, and ensure the cable shield is grounded at one end only to suppress ground loops. The DE and RE pins control driver/receiver direction; when using half-duplex, tie DE and /RE together with a single GPIO line. This page synthesizes distributor inventory, parametrically matched drop-in alternatives from the MAX48x family and competitive second sources, and practical design notes that go beyond what the manufacturer datasheet alone provides.

MAX6816EUS+T

MAX6816EUS+T - ±15kV ESD SOT-143-4 Switch Debouncer | Maxim

The Analog Devices / Maxim Integrated MAX6816EUS+T is a single-channel CMOS switch debouncer IC housed in a 4-pin SOT-143-4 surface-mount package, qualified over a 2.7 V to 5.5 V supply range and engineered for clean interfacing of mechanical switches to digital logic. It delivers a clean, debounced logic output from one bouncing mechanical input at 25 µA quiescent current with ±15 kV ESD protection on the switch input. A switch debouncer is a specialized interface IC that filters the mechanical contact bounce of switches, keypads, relays, or other electro-mechanical contacts so a downstream microcontroller or ASIC receives a single, deterministic logic transition. As a subcategory of supervisory / interface ICs, switch debouncers sit between the analog-mechanical input domain and the digital domain; they belong to the broader interface-IC hierarchy (specialized interface -> interface IC -> integrated circuit) and serve the same role as a hardware RC filter plus Schmitt trigger, but in a single chip. Key features of the MAX6816EUS+T include a fixed 40 ms (typical) debounce qualification delay that removes both switch opening and closing bounce, ±15 kV HBM ESD protection on the switch input per IEC 61000-4-2 air-discharge testing, 2.7 V to 5.5 V single-supply operation, low 25 µA quiescent current, and a small SOT-143-4 outline. The output stage is a CMOS push-pull driver capable of sourcing/sinking several milliamps, so it can directly drive most CMOS logic families without an external pull-up resistor. The MAX6816/MAX6817/MAX6818 family is fabricated on a low-power CMOS process with on-chip ESD cells and a precision timer block that sets the debounce interval without external capacitors. Compared to discrete RC + Schmitt debounce networks, the integrated timer is stable across temperature and removes the need for tuning. The MAX6818 (octal, 20-pin) is pin-compatible with the LS573 octal latch (except for the CH pin), giving a migration path for designers scaling from 1 channel to 8 channels. Typical applications of the MAX6816EUS+T include membrane keypad interfaces, pushbutton reset circuits, industrial control panels, automotive body controllers, portable consumer electronics, and appliance front-panel switches. The compact SOT-143-4 footprint makes it suitable where board area is constrained. When designing with this part, place a 0.1 µF decoupling capacitor within 5 mm of the VCC pin and keep the trace from the mechanical switch to the IN pin short to maximize ESD protection effectiveness. The output does not require a pull-up resistor. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes beyond what the manufacturer datasheet alone provides.

MAX71071+

MAX71071+ - 24-Bit Dual-Channel Isolated Metrology ADC | Maxim Integrated

The Maxim Integrated MAX71071+ (now under Analog Devices) is a 24-bit, dual-channel, isolated analog-to-digital converter (ADC) designed for high-precision metrology applications. Housed in a 10-pin uMAX/uSOP surface-mount package, the device pairs with a compatible MAX71xxx host to provide simultaneous current and voltage measurements. The host supplies control, command, and isolated power, while a pulse transformer provides the isolated data and clock path between the device and host, eliminating the need for additional optocouplers or digital isolators in the measurement subsystem. A metrology ADC is a high-resolution data converter optimized for energy metering, power-quality monitoring, and revenue-grade instrumentation. Compared with general-purpose ADCs, metrology converters emphasize DC accuracy, wide dynamic range, low noise, and excellent linearity over industrial temperature ranges. The MAX71071+ sits in the converter hierarchy as: ADC -> data converter -> signal chain IC -> analog/mixed-signal semiconductor. Key features include 24-bit resolution across two input channels, an integrated isolated interface through the host pulse transformer, simultaneous sampling of voltage and current channels, and a small 10-pin uSOP/uMAX footprint suitable for compact, isolated current-sensing modules. The device supports industrial temperature grades and is targeted at smart-meter, sub-metering, and power-monitoring designs where galvanic isolation and high accuracy are mandatory. The MAX71071+ uses an isolated SPI/dual-wire interface to the host, removing the requirement for external digital isolators. This architecture reduces BOM count, board area, and design complexity for isolated energy-measurement front ends. The companion host MAX71xxx device provides the isolated power rail to the secondary side via the pulse transformer, which also carries the bidirectional data between host and ADC. Typical applications include single-phase and polyphase electricity meters, branch-circuit power monitors, isolated current-sensing modules for industrial equipment, solar inverter string monitors, EV charging-station energy meters, and smart power strips. The integrated isolation simplifies safety compliance for line-voltage measurements. When designing with the MAX71071+, follow the datasheet reference layout for the pulse transformer and keep the secondary-side bypass network within the recommended geometry. A [DATA_NEEDED: full input bandwidth / sample rate] and [DATA_NEEDED: effective number of bits / SINAD] should be confirmed from the datasheet, since the available web snippets did not include complete AC performance numbers.

MAX71071+T

MAX71071+T - Dual 24-Bit Isolated ADC | Analog Devices

Analog Devices MAX71071+T is a dual-channel isolated 24-bit analog-to-digital converter designed for metrology measurements of current and voltage. The device communicates with a compatible MAX71xxx host through an integrated pulse-transformer isolation path and is supplied in a 10-uMAX/uSOP package. Its two measurement channels and isolated data, clock, and power interface support isolated sensing systems. An isolated ADC is an analog-to-digital converter whose measurement side is electrically separated from the control and processing side. This isolation limits the transfer of unwanted voltage and current between a high-voltage or high-current measurement environment and the host electronics. Within the signal-chain hierarchy, the MAX71071+T is a data-acquisition IC, an isolated ADC, and ultimately a metrology measurement component. The MAX71071+T provides two measurement inputs, 24-bit resolution, and simultaneous isolation through a pulse transformer. The pulse transformer carries the isolated data, clock, and power path, reducing the need for separate isolation components in the measurement subsystem. The host retains responsibility for control commands and the associated power supplied toward the measurement interface. This architecture is intended to measure current and voltage while maintaining an isolation barrier between the sensed quantities and the host. The exact input ranges, accuracy figures, sampling rate, power requirements, channel multiplexing arrangement, and timing characteristics should be confirmed against the relevant MAX71071 manufacturer documentation before setting the analog front end and system timing. Typical uses include isolated current monitoring, isolated voltage measurement, industrial metering equipment, power-system instrumentation, and other metrology systems that pair the converter with a compatible MAX71xxx host. The isolated interface is particularly useful when the measured circuit and the controller must remain galvanically separated. Designers should begin with the host-interface requirements, supported input ranges, and isolation ratings. Transformer-based isolation imposes timing and layout considerations around the measurement side, while host-side routing must preserve clock and data signal integrity. Component values, filtering, grounding, and creepage requirements should be derived from the application voltage, current, bandwidth, and safety environment. This product page combines the manufacturer product information, distributor listings, family relationships, and practical selection guidance to clarify where the MAX71071+T belongs in an isolated metrology design. It also distinguishes documented functions from parameters that require engineering confirmation before layout release.

MAX7219CNG

MAX7219CNG - 8-Digit LED Display Driver, 24-PDIP | Maxim

The Analog Devices (formerly Maxim Integrated) MAX7219CNG is a compact, serial-input/output common-cathode LED display driver that interfaces microprocessors to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Housed in a 24-pin PDIP (narrow, 0.300 inch / 7.62 mm) through-hole package, the device operates from a single +4.0 V to +5.5 V supply and includes on-chip BCD Code-B decoder, multiplex scan circuitry, segment and digit drivers, plus an 8x8 static RAM that stores the display state. A serial-in/serial-out LED driver is an interface IC that translates a high-speed synchronous serial data stream (SPI/QSPI/Microwire compatible on MAX7219) into multiplexed constant-current segment and digit outputs, eliminating the need for external current-limiting resistors on every LED. The MAX7219 belongs to the broader hierarchy LED display driver > display driver IC > interface IC > integrated circuit > semiconductor. Its integrated BCD decoder, multiplexing scan engine, and per-segment current control place it in the same functional family as the MAX7221 (SPI-only variant) and competitors such as Holtek HT16K33 and Titan Micro TM1637. Key features of the MAX7219CNG include an individual LED segment current programmable up to 40 mA per segment via a single external resistor (ISET), a 150 µA low-power shutdown mode (data retained), a scan-limit register that allows 1 to 8 digits, a digital brightness control (16 steps via 4-bit PWM duty cycle), and a display test mode that forces all segments on. The serial interface runs up to 10 MHz at +5 V, and the device cascades for additional digits by clocking the DOUT pin into the DIN of the next MAX7219. Typical applications are 8-digit 7-segment numeric readouts, 8x8 LED matrix modules (two cascaded MAX7219s drive a 64-LED matrix), bar-graph displays, industrial panel meters, scoreboard displays, and Arduino/AVR/PIC-based user interfaces. The MAX7219 is essentially the de-facto standard for hobbyist and educational LED matrix projects, with mature open-source libraries (LedControl, MD_MAX72XX, MD_Parola) supporting it. When designing with the MAX7219CNG, place a 0.1 µF bypass capacitor close to V+ and a 10 µF tantalum bulk capacitor on the supply rail, keep the ISET resistor within 9.53 kΩ (40 mA per segment) to 47 kΩ (10 mA per segment), and respect the 6 V absolute-maximum V+ rating. The narrow PDIP-24 footprint is identical to the MAX7221CNG and MAX7219CNG+ RoHS-compliant variant, so PCBs can be designed once and populated with either part.

MAX7456EUI+T

MAX7456EUI+T - Monochrome OSD Generator with EEPROM, 28-TSSOP-EP | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX7456EUI+T is a single-channel monochrome on-screen display (OSD) generator integrated circuit that combines a 256-character font ROM, non-volatile character memory (NVRAM), video sync separator, video driver, and SPI-compatible serial interface in a single 28-pin TSSOP-EP package. Designed for NTSC and PAL video systems, the MAX7456EUI+T displays up to 256 user-programmable 12x18-pixel characters at row 1 (top of frame), row 14 (middle), or row 26 (bottom), and integrates a video output driver that delivers a 2 Vp-p composite signal directly into a 75 ohm terminated load. An OSD (on-screen display) generator is a specialized mixed-signal IC that overlays text, graphics, and icons onto a composite video stream in applications where a graphical overlay is required without a full graphics controller. The MAX7456EUI+T belongs to the video processing IC family within the broader signal-chain and display-driver semiconductor hierarchy. It serves markets requiring character-based overlays in security camera menus, drone telemetry, industrial HMI, and consumer VCR/DVD equipment, eliminating the need for external video drivers, sync separators, switches, and EEPROM storage. This integration lowers system BOM cost, PCB area, and design risk. Key differentiating features include on-chip 256-character NVRAM (no external EEPROM required), built-in video output buffer (saves an op-amp), integrated sync separator for composite video or separate sync input, SPI serial control interface (compatible with 3.3 V and 5 V microcontrollers), and 2 Vp-p output drive into 75 ohm. The device operates from a single 5 V analog supply with a separate 3.3 V digital supply, supports 256 user-programmable characters, and provides automatic NTSC/PAL detection with 9.6 kB/s maximum character upload rate. Architecturally, the MAX7456EUI+T combines an analog video path (sync separator, clamp, video DAC, output buffer) with a digital control section (character memory, font ROM, address registers, SPI slave). The on-chip NVRAM uses Maxim's Zener-based non-volatile memory technology, which the manufacturer notes has a limited write endurance (specified in the datasheet). Designers should treat the NVRAM as configuration storage, not as a high-cycle-count working buffer. Typical applications include closed-circuit television (CCTV) and IP camera menu overlays, FPV drone OSD for telemetry and flight data, industrial machine vision HMI, set-top box user interface overlays, consumer VCR/DVD on-screen menus, and avionics or marine instrumentation display overlays. The MAX7456EUI+T suits any video-based system that needs non-volatile, persistent on-screen information without a full graphics processor. When designing with this device, verify NVRAM write endurance against expected menu-update frequency, and provide adequate decoupling on both the analog 5 V (VDD) and digital 3.3 V (VDD_DIG) rails to suppress switching noise coupling into the analog video output. Designers should also confirm the upstream video source provides proper sync polarity, as the MAX7456EUI+T expects NTSC/PAL standard composite video or separate HSync/VSync inputs. This page synthesizes distributor pricing, lifecycle status, and cross-reference guidance for the MAX7456EUI+T, including identification of the third-party AT7456E clone marketed as a drop-in substitute on certain distributor channels, and engineering considerations for transitioning away from this obsolete part.

MAX9100EUK+T

MAX9100EUK+T - 1.0V 5µA Micropower Comparator | Analog Devices

The Analog Devices MAX9100EUK+T is a single-supply micropower voltage comparator with 1.0V to 5.5V operation, 5µA quiescent current, and a 5-pin SOT-23 package. It is designed for battery-powered systems that require low-voltage decision-making without the higher supply requirement or current consumption of conventional comparators. A micropower comparator is a voltage-regulator-family analog semiconductor that compares two input voltages and produces a push-pull logic output indicating their relationship. The MAX9100 belongs to the comparator hierarchy and is used as a simple decision element, protection element, or threshold detector between an analog sensor and a digital system. Its low supply voltage and low quiescent current make it suitable for single-cell and coin-cell powered equipment. Key features include operation from a single 1.0V to 5.5V supply, 5µA quiescent current, rail-to-rail input capability, and an open-drain output according to the manufacturer comparison information. The common-mode input range includes the negative supply rail, which helps monitor low-voltage battery signals. The MAX9100EUK+T is specified in the 5-pin SOT-23 package and is supplied in tape-and-reel packaging. The MAX9100 is intended for low-energy signal-chain designs where the comparator must operate directly from a depleted battery or regulated low-voltage rail. Because its supply range begins at 1.0V, it can remain useful as the battery approaches its discharge endpoint. The device is optimized for single-cell systems rather than high-voltage industrial comparison tasks. Typical applications include battery threshold detection, portable sensor interfaces, low-voltage power sequencing, window or level comparison, and simple over-discharge indication. In these systems, the comparator can establish whether a measured voltage is above or below a reference without requiring a powered analog front end with a higher minimum supply. Designers should verify the exact output topology, input limits, propagation delay, and operating-temperature ratings against the current manufacturer datasheet before layout. Input and supply decoupling should be placed close to the device, and unused comparator inputs must not be left floating. The manufacturer application information is the authoritative reference for electrical limits and recommended usage. This product page combines verified manufacturer and distributor information with practical application guidance, pricing context, and design considerations that help engineers evaluate the MAX9100EUK+T for low-voltage battery systems.

MAX942CUA+T

MAX942CUA+T - 80ns High-Speed 3V/5V Comparator | Maxim

The Analog Devices / Maxim Integrated MAX942CUA+T is a single high-speed, low-power comparator optimized for 3V or 5V single-supply systems, housed in an 8-pin µMAX (uSOP) package. It combines 80 ns propagation delay with only 3 mA supply current per comparator and true rail-to-rail inputs that extend 200 mV beyond the rails. The CMOS push-pull / TTL-compatible output stage eliminates the need for an external pull-up resistor and swings rail-to-rail on the output side as well. A comparator is an analog decision-making element that compares two input voltages and drives its output to one of two saturated states; it is the 1-bit ADC of the analog domain, often used to translate an analog level into a digital logic edge for a microcontroller, ASIC, or FPGA. Comparators sit in the broader linear IC hierarchy: analog building block -> op-amp/comparator -> high-speed comparator -> rail-to-rail input comparator -> single-supply part. The MAX941/MAX942/MAX944 family from Maxim occupies the 3V/5V rail-to-rail comparator node of that hierarchy and is widely cited as the reference for low-power, fast-responding comparators in commercial-grade designs. Key features of the MAX942 include a 3 mV typical input offset voltage, 150 nA typical input bias current, 80 ns propagation delay, 3 mA supply current per comparator, push-pull CMOS/TTL-compatible output, and operation from 2.7 V to 5.5 V. It is specified over the 0 °C to +70 °C commercial temperature range in the MAX942CUA+T (uSOP-8) variant and is offered in tape-and-reel packaging with the +T suffix. The MAX942 uses a standard high-speed comparator architecture with input ESD-protection diodes, a low-offset input stage, and a CMOS push-pull output driver. The rail-to-rail input stage uses an N-channel / P-channel complementary differential pair that switches automatically as the common-mode voltage crosses the mid-supply region, preserving low distortion across the entire input range including 200 mV beyond VCC and GND. The push-pull output swings within millivolts of both rails for direct interfacing to 3V/5V CMOS logic. Typical applications include window detectors, threshold detectors, zero-crossing detectors, A/D front-ends, and line receivers in portable, industrial, and instrumentation equipment. Because the inputs remain linear 200 mV beyond both rails, the MAX942 is well suited to monitor a 5 V rail with a 5.5 V reference or to sense signals near ground with a single-supply design. When designing with this part, observe the absolute-maximum input current limit on the input ESD diodes and add a series resistor if a large overdrive is expected. The push-pull output cannot be wire-ORed with other open-drain outputs - if a shared interrupt line is needed, choose the open-drain MAX941 instead.

MAX9611AUB+

MAX9611AUB+ - 12-Bit High-Side Current-Sense Amplifier | Analog Devices

The Analog Devices MAX9611AUB+ is a high-side current-sense amplifier with an integrated 12-bit ADC and a configurable op amp or comparator gain block, operating from a 0V to 60V input common-mode range and offered in a 10-pin uMAX package. A high-side current-sense amplifier is an analog measurement IC that develops a voltage proportional to the current passing through a sense resistor placed in a supply or power rail. It belongs to the current-sense amplifier hierarchy within signal-chain and power-management semiconductors. By measuring voltage across a small shunt, the device enables current monitoring, protection, diagnostics, and feedback without interrupting the high-side load path. Key verified features include a 0V to 60V input common-mode range, programmable full-scale voltages of 440mV, 110mV, and 55mV, a 12-bit ADC, and 2.5MHz bandwidth identified in distributor product data. The MAX9611AUB+ uses the noninverting configuration identified by Analog Devices. Its integrated ADC supports digital current measurement, while the gain block can support comparator-style threshold functions according to the device documentation. The combination of a wide common-mode range and selectable full-scale voltage allows the sense resistor to be selected for the expected current range. This is useful when current measurements must operate across automotive, industrial, or power-supply rails while preserving measurement resolution. The 60V capability also exceeds the nominal range of many low-voltage signal-chain amplifiers, allowing the part to remain on a higher-voltage high-side rail. Typical applications include motor and actuator current monitoring, battery-pack current sensing, industrial power-system protection, DC-DC converter feedback, and automotive load diagnostics. The noninverting MAX9611 is appropriate when the measured output polarity and system architecture match the target board. Designers should verify the sense-resistor value, full-scale setting, ADC reference, Kelvin routing, filtering, and thermal dissipation before production. The manufacturer’s application guidance and datasheet should control the final values because the provided source data does not include all timing, accuracy, and electrical limits.

It is housed in a 100-pin TQFP (14x14 mm) package and operates from a single 2.7 V to 5.5 V supply, drawing a low quiescent current suited to multi-channel video routing cards and large switching arrays. A video crosspoint switch is an analog or digital signal-routing IC that allows any of N inputs to be switched to any of M outputs, typically with buffering on both sides so signals can drive long PCB traces or 75 ohm video loads. Crosspoint switches sit at the heart of video routers, production switchers, surveillance multiplexers, and broadcast equipment, replacing mechanical relays and discrete video amplifiers with a single silicon device. Programmable gain lets the designer compensate for cable losses or output-load variations across channels. The MAX9675ECQ+ integrates sixteen buffered inputs and sixteen buffered outputs with a fast SPI/QSPI-compatible 3-wire serial interface for matrix mode and per-channel gain programming. The BiCMOS process supports rail-to-rail video swings and wide bandwidth at low quiescent power, while on-chip clamp and bias circuitry preserves AC-coupled video baselines. All outputs are held in a high-impedance disabled state during power-up to avoid signal contention in multi-device arrays. Typical applications include broadcast video routers, professional video switchers, security and surveillance multiplexers, medical imaging pipelines, automotive infotainment video backbones, and test-and-measurement video generators. The wide supply range (2.7 V to 5.5 V) makes it compatible with both 3.3 V and 5 V logic, while the 110 MHz -3 dB bandwidth easily handles SD-SDI, composite, component, and RGBHV video formats. When designing, AC-couple inputs and outputs with 220 uF electrolytics and 0.1 uF ceramics, keep ground returns short and wide to preserve 110 MHz flatness, and program gain conservatively at +1 (0 dB) for cable-compensated long runs to avoid clipping into 75 ohm loads.
