ADM239LAR

ADM239LAR - 5V RS-232 Interface with DC-DC | Analog Devices

Analog Devices ADM239LAR is a 5 V powered CMOS RS-232 drivers and receivers IC with 3 driver channels, 5 receiver channels, 120 kB/s data rate, and an on-board DC-DC converter. It is packaged in a 24-lead SOIC measuring 0.295 inch, or 7.50 mm, wide. The device also provides low-power shutdown, 1 μF charge-pump capacitors, 9 V output swing from a 5 V supply, and receiver inputs rated to 30 V. An RS-232 transceiver is an interface IC that converts logic-level digital signals into differential, bipolar RS-232 signals and converts received RS-232 signals back into CMOS logic levels. The RS-232 transceiver belongs to the serial-interface hierarchy, which includes interface ICs, line drivers and receivers, communication transceivers, and broader data-communication semiconductors. It is designed for equipment-to-equipment communication over cables where voltage levels exceed ordinary CMOS input and output ranges. The ADM239LAR's principal advantages include operation from one 5 V supply, compliance with EIA-232-E and V.28 specifications, a maximum data rate of 120 kB/s, and an integrated DC-DC converter that generates the elevated RS-232 output voltage. Its 9 V output swing provides useful noise margin over the approximately 2 V RS-232 transition region. Low-power shutdown reduces consumption when the interface is not required, while the receiver remains active during shutdown. The integrated charge-pump circuit develops the bipolar transmitter voltage required by RS-232 from the single 5 V supply. The manufacturer datasheet specifies small 1 μF capacitors for the charge-pump circuit. Three transmitters provide enough channels for common control, status, and data paths, while five receivers allow the opposite direction of the link to carry several signals. The CMOS implementation supports integration into systems that already operate from 5 V rather than requiring the additional negative supply traditionally associated with RS-232. Typical uses include industrial control links, point-of-sale equipment, test and measurement instruments, data-acquisition systems, and embedded equipment interfaces. In each case, the ADM239LAR can translate between a 5 V controller and an external RS-232 port. The 120 kB/s rate is suitable for moderate-speed serial links, while the integrated DC-DC converter simplifies implementation where only a positive 5 V rail is available. The main design consideration is external line protection. Although the receiver input is specified to 30 V, exposed RS-232 ports may encounter larger transients or incorrect polarity. Appropriate surge and ESD protection should be added where the cable environment requires it, and unused driver outputs should be handled according to the manufacturer recommendations. This page consolidates the verified ADM239LAR specifications, sourcing information, procurement details, interface-application guidance, and data gaps that are not resolved by the supplied manufacturer and distributor records.

The ADM239LJR belongs to the line-driver and line-receiver hierarchy, which falls within interface ICs and broader digital and analog semiconductors. Its integrated charge-pump DC-DC converters provide the voltage needed for bipolar RS-232 output drive without requiring a separate 12 V supply. Key features include a single 5 V power supply, compliance with the EIA-232-E and V.28 specifications cited in the retrieved datasheet listing, a 120 kB/s data rate, and three drivers with five receivers. The on-board converters produce a 9 V output swing with a 5 V supply. Low-power shutdown reduces consumption when the interface is not needed, while 1 A receivers remain active during shutdown. The receiver input withstands voltages up to 30 V. The device combines a multichannel RS-232 line interface with internal power-conversion circuitry, reducing the number of external supply rails required by the board. Its CMOS implementation and specified 9 V swing target systems that must bridge short-distance, point-to-point serial links through single-ended RS-232. The combination of three drivers, five receivers, and shutdown behavior supports compact communications equipment where multiple serial lines and power conservation are important. Typical uses include industrial serial-port adapters, data-acquisition equipment, point-of-sale terminals, embedded control consoles, and instrumentation requiring RS-232 connectivity from a 5 V system. A transmitter converts outgoing UART or peripheral logic into RS-232 levels, while the five receivers allow multiple incoming lines to be monitored. The 120 kB/s rate is suitable for many legacy serial-control and data-transfer tasks when paired with a compatible UART and protocol. Designers should verify the external charge-pump capacitor values, UART signal levels, connector protection, and shutdown-state behavior against the Analog Devices datasheet before layout release. Keep RS-232 traces away from sensitive analog and high-speed digital paths, provide the specified bypass capacitance at the supply pins, and account for the 30 V receiver input limit when exposed to industrial wiring or ESD events. This page consolidates the verified ADM239LJR features, current distributor pricing references, package information, application guidance, and a transparent assessment of available drop-in alternatives. It also distinguishes documented device capabilities from fields not supplied by the retrieved sources, preventing unverified electrical claims from being presented as manufacturer specifications.

The two-channel arrangement is particularly useful when a system needs both transmit and receive paths on each of two RS-232 ports while keeping the external component count low. When laying out a design, place the charge-pump capacitors close to their designated pins and provide a clean 5 V supply with local high-frequency bypass. RS-232 is an unbalanced interface, so cable routing and grounding can affect noise immunity. Confirm that the selected connector, cable, and remote equipment use compatible RS-232 signal levels before deployment. This page combines the verified ADM242ANZ specifications, package information, sourcing guidance, and practical interface-design considerations. It also distinguishes the available pin-compatible family option from broader functional equivalents, helping engineers assess replacement decisions without changing the PCB footprint.

The verified operating-temperature range is -40°C to +85°C, making the device suitable for industrial-temperature equipment when other system requirements are satisfied. The on-chip charge pump avoids a discrete negative-voltage supply and supports a compact interface implementation. In an RS-232 application, the CMOS-side pins connect to a UART or another serial controller, while driver outputs connect through the cable or board-level interface and receiver inputs accept the remote signal. The supply and charge-pump capacitor network must be placed according to the manufacturer datasheet because their stability and layout affect communication reliability. Typical uses include industrial serial adapters, instrumentation, data-acquisition equipment, embedded serial links, and control systems requiring more than one RS-232 direction. The ADM242AR is appropriate when two transmit and two receive channels are needed in one 5 V interface. Because its data rate is specified up to 200 kbps, cable length, termination, grounding, and connector requirements should be evaluated together with the UART baud rate. For new layouts, reserve all 18 package pins, connect the charge-pump capacitors as specified by Analog Devices, and provide a local bypass capacitor near the supply pins. The verified SOIC-18 footprint should be checked against the selected board and the exact ADM242AR pinout. Designers should confirm RS-232 electrical requirements, shutdown or enable behavior, and system-level ground strategy before release. This page combines the verified Analog Devices product description, distributor package and price references, and cross-reference results to help engineers evaluate the ADM242AR.

ADM2482EBRWZ

ADM2482EBRWZ - 2.5kV Isolated RS-485/RS-422 Transceiver | ADI

The Analog Devices ADM2482EBRWZ is a 2.5 kV rms isolated RS-485/RS-422 transceiver with integrated transformer driver, ±15 kV ESD protection, and 16 Mbps data rate, packaged in a 16-lead wide-body SOIC (SOIC-W). It combines a three-channel digital isolator, an RS-485/RS-422 differential line driver, and a differential line receiver on a single die, eliminating the need for an external DC/DC isolation supply by deriving bus-side power from an external center-tapped transformer. What is an isolated transceiver? An isolated transceiver is a type of interface IC that combines a galvanic isolation barrier with a standard serial communication protocol transceiver. It belongs to the broader family of digital isolators -> interface ICs -> wired communication transceivers -> semiconductors. The galvanic isolation (typically 2.5 kV rms or higher) protects low-voltage logic and host circuitry from large ground-potential differences, surge events, and fault voltages on long industrial bus segments. Isolated transceivers are essential when RS-485 cabling leaves the local equipment chassis and traverses factory floors, process plants, or outdoor installations. Key features of the ADM2482EBRWZ include a 25 kV/µs common-mode transient immunity (CMTI), 16 Mbps maximum data rate (suitable for PROFIBUS and high-speed half/full-duplex RS-485), configurable half-duplex or full-duplex operation, and a 3.3 V/5 V logic-side supply with a 3.3 V isolated bus-side supply generated internally from pins D1/D2 driving an external transformer. The wide-body SOIC package provides the required 8 mm creepage clearance for 2.5 kV rms reinforced isolation per IEC 61850 / IEC 61010-1 system standards. Hot-swap glitch rejection on the DE and RE pins prevents data corruption during board insertion into a live backplane. The transceiver uses an iCoupler-style transformer-driven isolation architecture: logic-side data crosses the isolation barrier through ADI's chip-scale micro-transformers, and bus-side power is rectified from a secondary winding. This architecture eliminates optocoupler LED aging concerns and provides stable timing across the industrial temperature range. The device operates over -40 °C to +85 °C ambient and meets ±15 kV ESD per IEC 61000-4-2 air-gap discharge on the bus pins. Typical applications include isolated RS-485 nodes in industrial fieldbus networks (PROFIBUS DP, Modbus RTU), smart-grid metering and substation communications, building automation (BACnet, KNX), solar inverter CAN/RS-485 links, and any system requiring robust high-voltage isolation between a controller and a remote bus segment. Half-duplex mode uses pins Y/Z/A/B; full-duplex mode uses dedicated TX and RX differential pairs. When designing with the ADM2482EBRWZ, pay attention to the center-tapped transformer selection: a 1:1.33 to 1:1.5 turns ratio with adequate isolation rating is recommended. Place the Schottky diodes and smoothing capacitor close to pins D1/D2 for clean bus-side power, and use 120 Ω termination at both ends of the RS-485 bus. The wide-body SOIC footprint requires an 8 mm minimum clearance under the package for 2.5 kV rms reinforced isolation.

ADM2561EBRNZ

ADM2561EBRNZ - 3kV Isolated RS-485 Transceiver, 25Mbps | ADI

The Analog Devices ADM2561EBRNZ is a 3 kV RMS signal and power isolated RS-485 transceiver with integrated isoPower isolated DC-DC converter, housed in a 28-pin SOIC-W-FP wide-body package with exposed pad. It supports full- and half-duplex communication at data rates up to 25 Mbps while providing ±15 kV IEC ESD protection on the bus pins. An isolated RS-485 transceiver combines a standard RS-485 line driver/receiver (TIA/EIA-485-A and ISO 8482:1987 compliant) with galvanic isolation between the logic-side UART and the bus-side cable. The isolation barrier, typically 3 kV RMS for 60 seconds, breaks ground loops, protects low-voltage processors from hazardous bus voltages, and rejects common-mode transients on long industrial cable runs. When the transceiver also integrates an isolated DC-DC converter (isoPower), the device only needs a single 3.3 V or 5 V supply on the logic side - the high-voltage bus-side rails are generated internally. Key features include 3 kV RMS basic isolation per UL 1577, integrated isolated DC-DC converter, ±15 kV IEC 61000-4-2 ESD on the bus pins, 25 Mbps maximum data rate, 1/8 unit load (256 nodes on the bus), and hot-swap tolerant driver outputs. The SOIC-W-FP (wide-body SOIC with exposed pad) package provides 8 mm creepage/clearance on the PCB and excellent thermal dissipation for the internal DC-DC converter. Typical applications include isolated RS-485/RS-422 industrial fieldbus nodes (Modbus, PROFIBUS, BACnet), solar inverter string monitoring, building automation gateways, motor drive control interfaces, and any system that needs to bridge a high-voltage or noisy bus to a low-voltage microcontroller over a safety-rated isolation barrier. When designing with the ADM2561EBRNZ, follow the datasheet PCB layout guidelines for the exposed pad and the clearance/creepage rules of the 8 mm wide-body SOIC. Decoupling capacitors must be placed close to the VDD1/VISOIN/VISOOUT pins; failure to do so can degrade the internal DC-DC converter's noise performance.

It integrates an isolated DC-to-DC converter and an isolated RS-485 transceiver in a single IC, supports full- and half-duplex operation, and is rated for ±15 kV IEC ESD on the bus pins. An isolated RS-485 transceiver is a physical-layer interface IC that combines galvanic isolation with a differential line driver/receiver. Isolation breaks ground loops between the local controller (MCU, FPGA, processor) and the remote bus nodes, allowing long cables, large common-mode voltages, and improved noise immunity in industrial systems. The ADM2561E family complies with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E), placing it within the RS-485 transceiver product hierarchy: RS-485 transceiver -> line transceiver -> interface IC -> integrated circuit. Key features include 3 kV RMS isolation per UL 1577, integrated isolated DC-DC converter (no external transformer required), up to 25 Mbps data rate, and a 1-channel full-/half-duplex topology. The transceiver operates from a single 3 V or 5 V supply on the logic side, with the bus side powered through the integrated isoPower converter. Receiver failsafe features guarantee a known output state on idle or shorted bus, and the device supports up to 256 nodes on a single bus. Wide-body SOIC-W-FP provides 8 mm of creepage/clearance for reinforced isolation. The architecture uses ADI's iCoupler technology: chip-scale transformers for both signal isolation (coreless digital isolation) and power isolation (isoPower integrated DC-DC). This eliminates the need for a discrete isolation barrier plus separate isolated supply, saving ~50% PCB area versus discrete solutions. Latency is typically <100 ns per channel, making the device adequate for high-speed industrial protocols such as Profibus, Modbus RTU, and high-speed motion-control networks. Typical applications include industrial fieldbus nodes (Modbus, Profibus, BACnet), solar inverter string monitoring, building automation gateways, motor-control encoder links, and any long-cable RS-485 link where ground potential differences exceed ±10 V. The integrated isoPower allows single-supply designs, simplifying bill-of-materials for isolated nodes. Designers should budget for the SOIC-W-FP land pattern and observe creepage/clearance constraints for reinforced isolation. The exposed pad must be soldered to a sufficiently large copper island connected only to the logic-side ground or left floating per safety certification. This page synthesizes distributor pricing, drop-in alternatives, and engineering guidance not found in the standalone datasheet, helping procurement and design engineers evaluate the ADM2561EBRNZ-RL7 faster.

Key features of the ADM2563EBRNZ include an integrated isolated DC-DC converter (no external transformer required), ±15 kV IEC 61000-4-2 ESD on RS-485 A/B/Y/Z pins, ±25 kV HBM ESD on bus pins, 25 Mbps maximum data rate, thermal shutdown, and current-limit protection on the isolated supply output. The 28-SOIC-W-FP package (wide-body SOIC with an exposed pad for thermal dissipation) is rated to 3 kV RMS (per IEC 61010-1 / UL 1577) for reinforced isolation. The exposed pad must be soldered to the PCB ground plane to achieve the rated creepage/clearance and to limit junction temperature rise at full duplex load. Typical applications include isolated RS-485 industrial fieldbus nodes, solar inverter monitoring, building automation (BACnet, Modbus RTU), motor drive encoder feedback, and any point-to-point or multi-drop RS-485 link requiring 3 kV reinforced isolation. The ADM2563EBRNZ is particularly attractive when PCB area is constrained because it eliminates the transformer, optocouplers, and isolated LDO that a discrete isolation solution would otherwise require. When designing with this part, observe the exposed-pad soldering guideline, decouple VCC/VIO/VISOOUT with 1 µF X7R ceramics placed within 2 mm of each pin, and confirm that the bus-side shield/ground reference matches the application. The integrated isolated DC-DC converter removes the need for a push-pull transformer but does introduce about 25 mA quiescent current draw from VCC.

ADM2565EBRNZ-RL7 - 3kV Isolated RS-485 Transceiver, 25Mbps | ADI

The Analog Devices ADM2565EBRNZ-RL7 is a 3 kV rms signal-and-power isolated RS-485 transceiver supporting data rates up to 25 Mbps in a 28-lead SOIC_W wide-body fine-pitch package with integrated isoPower isolated DC-DC converter. The device integrates a half-duplex RS-485 driver/receiver pair, an on-chip transformer-based power isolator, and ±15 kV IEC ESD protection on the bus pins, eliminating the need for a separate digital isolator and isolated supply. According to the Analog Devices ADM2565E family datasheet, the part complies with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987 (E) for balanced transmission lines. What is an isolated RS-485 transceiver? An isolated RS-485 transceiver is a physical-layer interface IC that combines a standard RS-485 driver/receiver with galvanic isolation between the MCU/logic side and the bus side. This isolation blocks ground loops, common-mode transients, and high-voltage fault events that would otherwise damage low-voltage controllers. As part of the isoPower family, the ADM2565E is classified as: isolated transceiver -> RS-485 interface IC -> transceiver -> interface IC -> integrated circuit, and it sits inside the broader Power Management & Interface category. Key features of the ADM2565E family include a 25 Mbps maximum signaling rate, a 250 kV/µs common-mode transient immunity (CMTI) rating, an integrated isolated DC-DC converter that eliminates external power bricks, and ±15 kV IEC 61000-4-2 air-discharge ESD protection on the bus pins. The wide-body SOIC_W_FP package (10.15 mm × 10.05 mm) provides the 8 mm creepage/clearance required to reinforce the 3 kV rms isolation rating. Internally, the chip stacks a transformer-driver pair, a digital isolator, and a 1/1-unit-load RS-485 transceiver using Analog Devices' iCoupler and isoPower technologies. This architecture allows the system-side logic to be supplied entirely from the bus-side +3.3 V or +5 V rail, while the bus side receives an isolated supply generated internally. Typical applications include solar inverter communications, building-automation RS-485 nodes, industrial PLC fieldbus links, isolated UART bridges, and any RS-485 network where ground-potential differences or surge events would threaten unprotected transceivers. Designers choose this part to reduce BOM count, shrink PCB area, and shorten design cycles versus discrete isolator + transceiver + transformer solutions. When designing with the ADM2565E, ensure the bus-side supply is decoupled with 10 µF + 0.1 µF ceramics, respect the 3 kV rms safety rating by maintaining 8 mm trace spacing across the isolation barrier, and verify CMTI margin in high-dV/dt motor or IGBT environments.

It supports data rates up to 25 Mbps across four channels of signal isolation plus isolated power, and is rated for ±15 kV IEC 61000-4-2 ESD on the bus pins, ±6 kV IEC 61000-4-2 contact discharge on the A, B, Y, Z pins, and 250 kV/µs common-mode transient immunity (CMTI). The transceiver complies with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987 (E) for balanced transmission lines. A digital isolator with integrated isolated power is a single-package solution that combines galvanic isolation between the logic-side controller and the bus-side transceiver with an on-chip DC-DC converter, eliminating the need for an external isolated supply. This category sits inside the broader hierarchy: digital isolator → interface IC → integrated circuit → semiconductor. By embedding the isolated DC-DC, the ADM2567EBRNZ collapses two BOM items (an isolated RS-485 transceiver plus a discrete isolated supply) into one IC, saving PCB area and simplifying the safety-certification paperwork for IEC 60950 / IEC 62368-1 reinforced insulation. Key features include 1.7 V to 5.5 V VIO logic-side supply, a wide-bus supply range supported through the integrated isolated DC-DC, hot-swap capable bus pins, slew-rate-limited driver options in the slower family members, and full fail-safe receiver inputs. The half-duplex/full-duplex topology and 25 Mbps maximum signaling rate make the part suitable for industrial fieldbus networks where high noise immunity and high throughput are simultaneously required. Typical applications include PROFIBUS and Modbus nodes, isolated RS-485 links in factory automation, solar inverter communication buses, building-automation gateways, and any system that needs to meet IEC 61000-4-2 air-discharge Class B or IEC 61000-4-5 surge standards without an external TVS array. When designing with this part, follow the PCB layout recommendations in the ADM2561E/63E/65E/67E datasheet - particularly the placement of the decoupling and bypass capacitors across the integrated DC-DC and the creepage/clearance guidance that is built into the wide-body SOIC footprint.

It is part of the iCoupler family and combines an isolated RS-485 driver/receiver pair with an LDO-regulated isolated power supply, eliminating the need for an external DC-DC isolation transformer in many designs. An RS-485 transceiver is a differential line driver/receiver IC used for robust, long-distance, half- or full-duplex serial communication over twisted-pair cabling in electrically noisy environments. Galvanic isolation (here, 5.7 kV rms) separates the controller-side logic ground from the bus-side ground, protecting low-voltage MCUs and protecting downstream nodes from large common-mode voltages, ground loops, and surge events. iCoupler technology is Analog Devices' transformer-based digital isolation, achieving high CMTI and low EMI compared to optocoupler-based isolation. Key features include ±15 kV IEC ESD protection on the bus pins, 250 kV/µs common-mode transient immunity (CMTI), 4-channel (3/3 or similar logic-side) signal path, and compliance with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E). The on-chip isolated power delivers an LDO-regulated 3.3 V or 5 V to the bus side from a single 3 V to 5.5 V controller-side supply, simplifying BOM and PCB layout. The architecture stacks a digital isolator + RS-485 transceiver + isoPower transformer/rectifier/regulator in one SSOP-28. Compared to discrete optocoupler + isolated DC-DC designs, ADM2865EBRNZ cuts BOM count by ~10-15 parts, shrinks board area, and ensures matched propagation delay and CMTI performance validated by the manufacturer. Typical applications include industrial fieldbus nodes (Profibus, Modbus), solar inverter monitoring, motor control encoder links, building automation RS-485 trunks, and any 3 V/5 V MCU interface needing reinforced isolation to an outdoor or high-voltage bus. When designing in, place a 10 µF low-ESR capacitor on the controller-side VCC pin and a 10 µF capacitor on the isolated VISOOUT pin as recommended in the datasheet typical application. Do not exceed 25 Mbps if the bus is long (>10 m); derate data rate vs. cable length per RS-485 propagation guidelines.

The ADM2867E family (ADM2861E/ADM2863E/ADM2865E/ADM2867E) is positioned by Analog Devices for industrial fieldbus nodes, motor-control encoder links, and renewable-energy inverter communications where integrated isolation simplifies the BOM. Key specifications include 5.7 kV RMS isolation per UL 1577 (signal + power channels), 25 Mbps maximum data rate, ±15 kV IEC 61000-4-2 ESD on the bus pins, and compliance with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987 (E). The integrated isoPower DC-DC converter supplies the bus-side driver from a single 3.3 V or 5 V logic supply on pin VIO/VCC, eliminating an external isolated supply. The wide-body SOIC package with >8.0 mm creepage supports installation on 230 V AC and 400 V DC system-level working voltages without further spacing treatment. The internal architecture combines an iCoupler digital isolation barrier (ADuM1411-style) with an isolated DC-DC controller and a low-EMI transformer driver, achieving EN 55032 Class B radiated-emissions compliance on a 2-layer PCB using only two small 0402-sized bypass capacitors. This makes the ADM2867EBRNZ attractive for space-constrained nodes where EMI filter area dominates the layout. Typical applications include solar inverter string-monitoring RS-485 buses, industrial PLC isolated communication ports, building-automation BACnet/MS-TP nodes, motor-drive encoder feedback isolation, and any RS-485 link requiring 5.7 kV reinforced isolation across the bus interface. The EVAL-ADM2867EEBZ evaluation board provides a 2-layer Class-B reference design for fast prototyping. When designing with the ADM2867EBRNZ, observe the >8.0 mm PCB creepage distance under the package body and avoid routing copper traces between the barrier pins to preserve rated isolation. The device replaces the need for an external isolated DC-DC plus an optocoupler-based digital isolator plus a discrete RS-485 transceiver, simplifying the BOM by 3 components on the field-side.

ADM3051BRWZ-RL7 is an Analog Devices controller area network (CAN) physical layer transceiver that provides a robust interface between a CAN protocol controller and the two-wire CAN bus. It operates from a single 5 V VCC supply, complies with the ISO 11898 standard, and supports high-speed data rates up to 1 Mbps. The device is offered in an 8-lead SOIC package and is supplied in tape-and-reel packaging for high-volume assembly. What is a CAN transceiver? A controller area network (CAN) transceiver is an interface IC that converts logic-level signals from a CAN controller into the differential signals required on the CANH and CANL bus lines, and vice versa. It sits between the protocol controller and the physical twisted-pair bus, providing the required differential drive, receive sensitivity, and protection functions. In the system hierarchy, a CAN transceiver is part of the physical layer in a CAN network, below the data-link and application layers. The ADM3051 is a non-isolated, single-channel half-duplex transceiver intended for industrial and automotive networks where ISO 11898 compliant communication at up to 1 Mbps is required. Key features of ADM3051BRWZ-RL7 include short-circuit protection on CANH and CANL for shorts to power or ground in 24 V systems, operation with unpowered nodes that do not disturb the bus, and capability to connect 110 or more nodes. It also provides slope control on the RS pin to reduce radiated EMI, thermal shutdown protection, and a low-current standby mode for power-sensitive applications. These features make it a physically robust PHY for noisy or high-node-count environments. Technically, the ADM3051 is a CAN physical-layer IC in the Analog Devices ADM305x family. It uses a differential bus interface and includes bus fault protection and thermal shutdown in a single 8-pin SOIC package. The -RL7 suffix denotes 7-inch reel tape-and-reel packaging, and the BRWZ code indicates the lead-free (Z) SOIC (RW) package variant. The device is designed for 5 V-only systems, simplifying power supply design and enabling direct interface to 5 V CAN controllers without extra level shifting. Typical applications include industrial automation PLCs, automotive body electronic modules, building management system controllers, battery management systems, medical equipment and CAN data logging nodes. In each of these, the ADM3051's 1 Mbps speed, 110+ node bus capability, and short-circuit protection reduce risk of fieldbus faults while maintaining simple 5 V power architecture. When designing with ADM3051BRWZ-RL7, place a 120 ohm termination resistor between CANH and CANL at both ends of the bus and set the RS pin resistor to control the slew rate for EMI optimization. For best decoupling, use a 100 nF ceramic capacitor close to VCC and a bulk capacitor at the supply point.

ADM3052BRWZ-RL7

ADM3052BRWZ-RL7 - Isolated CAN Transceiver 5kV | ADI

The Analog Devices ADM3052BRWZ-RL7 is an isolated Controller Area Network (CAN) physical layer transceiver with an integrated linear regulator, supplied in a 16-lead SOIC (SOIC-W) package on 7-inch tape and reel. It complies with ISO 11898 and uses Analog Devices iCoupler technology to combine a 3-channel digital isolator and a CAN transceiver in one package. The device supports data rates up to 1 Mbps and provides 5 kVrms signal isolation. An isolated CAN transceiver is an interface IC that places a galvanic isolation barrier between the logic-side CAN controller and the physical bus-side transceiver. In a CAN node, the controller sends TXD/RXD signals across the isolation barrier to the transceiver, which then drives the differential CANH and CANL bus lines. This prevents ground loops, common-mode voltages, and transient noise in industrial or automotive networks from disturbing the local microcontroller. The transceiver sits in the signal chain between the CAN controller and the twisted-pair bus, making isolation a key reliability requirement in harsh environments. Key features of the ADM3052 family include 5 kVrms isolation voltage, a 1/1 driver/receiver configuration, 1 Mbps ISO 11898-compliant data rate, and a logic-side supply of 3.3 V or 5 V. The integrated linear regulator enables bus-powered operation from a 24 V-class V+ rail, eliminating the need for a separate isolated DC-DC converter in many nodes. The 16-lead SOIC wide-body package supports surface-mount assembly and automated tape-and-reel production. From a design perspective, the ADM3052 integrates the isolation barrier, CAN transceiver, and LDO regulation into one package, simplifying PCB layout and reducing component count. The iCoupler technology provides common-mode transient immunity that is critical for reliable CAN communication in motor drives, battery packs, and factory-floor networks. Because the bus side can be powered directly from V+, the node can be designed as a two-wire bus-powered device in applications where a standalone isolated supply is not economically justified. Typical applications include automotive electronic control units, battery management systems, industrial CANopen networks, building automation, medical monitoring equipment, and test instrumentation. The combination of 5 kVrms isolation and bus-powered regulation makes the ADM3052 especially useful in distributed sensor nodes that must survive ground potential differences. When designing with this device, pay attention to the input voltage range and dropout of the integrated linear regulator, and place adequate bypass capacitance on the V+ and logic-side rails. The isolation barrier also requires proper PCB creepage and clearance to maintain the specified 5 kVrms withstand voltage.

It integrates one driver and one receiver and is designed for full- and half-duplex communication on multipoint bus transmission lines, supporting data rates up to 250 kbps per the ADM307xE family specification. A RS-485/RS-422 transceiver is a differential line interface IC that converts between a single-ended UART/logic signal on the controller side and a robust differential signal on the cable side. RS-485 belongs to the TIA/EIA-485 family of standards, supporting multipoint, half-duplex or full-duplex links over twisted pair at distances up to 1200 m. Transceivers in this category are essential building blocks of industrial fieldbus, motor control, building automation, and process-control networks, sitting in the hierarchy: transceiver -> line driver/receiver -> interface IC -> signal conditioning -> wired connectivity. Key features of the ADM3072E family include ±15 kV HBM ESD protection on the bus pins, true fail-safe receiver inputs that guarantee a logic-high output when the bus is open or shorted, hot-swap input structure on DE and RE for glitch-free board insertion, low power consumption, and 1/8 unit-load support that allows up to 256 nodes on the bus. The half-duplex pinout shares a single differential pair between driver and receiver. The device operates from a single 3.0 V to 3.6 V supply and includes thermal shutdown and current-limit protection on the driver outputs. Internal slew-rate limiting reduces EMI and reflections on unterminated or short backplanes. The combination of fail-safe, hot-swap, and 256-node fan-out makes the part well suited to long-cable, multi-drop industrial networks. Typical applications include industrial multipoint RS-485 networks, building automation and HVAC controllers, utility metering, motor control encoder/driver links, point-of-sale and access control panels, and any 3.3 V MCU/UART-to-RS-485 bridge. Pairing with a 3.3 V Cortex-M MCU (e.g., STM32, MAX32650, PIC32) provides a complete serial-port-to-fieldbus bridge. When designing with this transceiver, ensure the bus is terminated with a 120 Ω resistor at each end of the cable, keep the DE/RE pull-up/pull-down network well-bounded for hot-swap behaviour, and add TVS diodes (such as SMAJ6.8CA) for surge protection beyond the built-in ±15 kV HBM ESD rating.

ADM3202AN

ADM3202AN - 3.3V Dual RS-232 Transceiver | Analog Devices

Analog Devices ADM3202AN is a dual-channel RS-232 and CCITT V.28 interface transceiver operating from a single 3.3 V supply, with a data rate up to 230 kbps according to the manufacturer product page. The device integrates two RS-232 line drivers and two receivers and uses four external 0.1 µF charge-pump capacitors to generate the bipolar voltages required by the RS-232 interface. It is supplied in a 16-pin PDIP package. An RS-232 transceiver is an interface IC that translates between single-ended logic-level signals and the bipolar, single-ended signaling used by RS-232 equipment. Within the interface hierarchy, the ADM3202AN belongs to the RS-232 transceiver family of communication interface ICs. Its 3.3 V operation is useful for portable, battery-powered, industrial, and embedded systems where a higher-voltage RS-232 supply would increase power consumption or complicate system design. Key features include operation from one 3.3 V supply, support for data rates up to 230 kbps, compliance with the EIA-232E and CCITT V.28 specifications, and four external 0.1 µF charge-pump capacitors. The Analog Devices family also offers PDIP, SOIC, SSOP, and TSSOP package options. These characteristics make the ADM3202AN suitable for industrial data links, point-of-sale equipment, instrumentation, and other systems that need bidirectional serial communication over RS-232. The internal charge-pump and voltage-doubler circuitry lets the device operate without a separate negative supply. Designers must nevertheless preserve the required capacitor connections and provide suitable bypass capacitance close to the supply pins. Because an RS-232 receiver commonly includes hysteresis and threshold behavior, signal integrity depends on correct grounding, cable routing, and protection practices at the connector rather than on high-speed digital routing techniques. The ADM3202AN is appropriate for legacy serial-console connections, test and measurement control interfaces, payment terminals, industrial control panels, and communication links between a 3.3 V embedded controller and an RS-232 peripheral. The 16-pin PDIP package is also useful for prototypes, through-hole industrial products, and designs that favor inspection or socket assembly rather than a surface-mount layout. A critical design consideration is the availability of the obsolete ADM3202AN. The exact listed unit price is $1.75 as of 2026-10-28, but lifecycle status and sourcing should be confirmed before committing a new production design. Engineers should also verify charge-pump capacitor voltage ratings, provide adequate supply decoupling, and protect externally accessible RS-232 lines against electrostatic discharge. This page consolidates the verified manufacturer specifications, distributor pricing, package information, and available drop-in references for ADM3202AN. It also highlights the lifecycle risk, practical charge-pump requirements, and the exact application conditions under which each substitute should be selected.

The Analog Devices ADM3202ARNZ-REEL7 is a low-power, 2-driver/2-receiver RS-232/V.28 line transceiver that operates from a single +3.3 V supply, supports data rates up to 460 kbps, and uses only four external 0.1 uF charge pump capacitors, housed in a 16-pin SOIC (0.154 in / 3.90 mm width) package supplied on tape and reel. An RS-232 transceiver is an interface IC that converts logic-level UART signals (TTL/CMOS, typically 0 V to 3.3 V) to the higher voltage swings defined by the EIA-232E and ITU V.28 standards, and vice versa. Within the signal-chain hierarchy, it belongs to the interface IC family alongside RS-485, CAN and USB transceivers, and sits between a microcontroller UART and a physical D-sub serial port. Because RS-232 rails can swing to +/-5 V or more, an integrated charge pump (voltage doubler and inverter) is required when only a single low-voltage supply is available. Key features of the ADM3202 include guaranteed 460 kbps operation for high-speed serial links, operation from a 3 V to 5.5 V supply range per distributor parametric data, EIA-232E/V.28 conformance, and a small external capacitor requirement of only 4 x 0.1 uF, which reduces board area and BOM cost. The complementary ADM3222/ADM1385 family members add a low-power shutdown facility for battery-powered portable instruments. Technically, the device uses CMOS charge-pump technology with integrated driver and receiver channels. The charge doubler generates V+ and the inverter generates V- from the 3.3 V rail, enabling true RS-232 output levels without a dual supply. Receivers incorporate hysteresis and tolerate input voltages up to +/-30 V, improving noise immunity on long cables. Typical applications include industrial point-of-sale equipment, networking and communication equipment serial management ports, embedded systems console/debug ports, and battery-powered portable instruments with RS-232 connectivity. Design considerations: place the four 0.1 uF charge pump capacitors as close as possible to pins 1-6, and use at least 0.1 uF of supply decoupling on VCC; note the ADM3202 itself lacks the shutdown pin available on the ADM3222 variant. This page synthesizes distributor availability, drop-in alternatives, pinout detail and design notes beyond what a single datasheet provides.
