ADM211AR

ADM211AR - 4/5 RS-232 Transceiver, 120 kbps | Analog Devices

The Analog Devices ADM211AR is a 4-driver, 5-receiver RS-232 transceiver designed for EIA-232-E and V.28 communications from a single 5 V supply. It supports data rates up to 120 kbps, uses 0.1 µF charge-pump capacitors, and provides approximately ±9 V output swing in a 28-pin SOIC package. The integrated dc-to-dc converters eliminate the need for a separate ±12 V supply. An RS-232 transceiver is an interface IC that converts between digital logic levels and the bipolar voltage levels used by RS-232 links. It belongs to the broader line-driver/receiver and interface-IC hierarchy, where differential or single-ended digital signals must cross systems with different voltage references. The ADM211AR combines four transmit channels and five receive channels for multi-port equipment, industrial controllers, and legacy peripheral connections. Key features include four drivers, five receivers, operation from a 4.5 V to 5.5 V supply, and a data rate of 120 kB/s. The on-board dc-to-dc converters support approximately ±9 V output swing from a 5 V supply, while the low-power mode is specified at 15 mW. The receiver section provides 30 V input-level handling according to the supplied search data, making the device useful where protected or long RS-232 lines are encountered. The ADM211AR is designed for EIA-232-E and V.28 interfaces when ±12 V is unavailable. Its 28-SOIC package provides a conventional surface-mount footprint and allows the four transmitters and five receivers to be consolidated instead of using separate interface devices. The exact pin assignments, absolute maximum ratings, propagation timing, and detailed electrical limits must be confirmed in the manufacturer datasheet before layout or production use. Typical applications include RS-232 port expansion, industrial data acquisition, test equipment, instrumentation, and embedded serial interfaces. In a multi-port design, the four drivers can support outgoing connections while five receivers provide additional inbound channels. The shared supply architecture also simplifies system design where a single 5 V rail is available. A key design consideration is maintaining the correct charge-pump capacitor values and checking the RS-232 line polarity and signal levels during bring-up. Decoupling should follow the manufacturer application guidance, and unused channels should be configured according to the datasheet rather than left floating. The device is a digital interface IC, so SOA is not applicable. This product page consolidates verified manufacturer and distributor information, application guidance, sourcing context, and engineering design notes. It distinguishes verified facts from parameters that still require the complete manufacturer datasheet, helping engineers evaluate the ADM211AR without relying on unverified substitutions.

The ADM222 provides 2 drivers and 2 receivers, enabling two simplex links or one full-duplex RS-232 port. Its 200 kbps transmission rate is substantially faster than conventional low-speed RS-232 links. A 5 V-only power architecture simplifies system supply design, while the external 0.1 µF charge-pump capacitors support generation of bipolar signal levels. The stated 9 V output swing provides the required positive and negative line-drive voltage. The receiver input rating extends to 30 V, providing useful transient and voltage-range margin when connected to external RS-232 equipment. The device also includes a shutdown pin, allowing the transceiver to reduce activity when the interface is not required. Exact propagation-delay, input-threshold, output-current, supply-current, and temperature values are not present in the supplied search data and therefore require confirmation from the manufacturer datasheet. Typical uses include industrial serial-control links, test equipment, instrumentation, data-acquisition systems, and legacy peripheral connections. In each case, the two receiver/driver channels can support bidirectional communication when TX and RX signals are crossed appropriately. The 200 kbps rate can also shorten transfer time compared with slower RS-232 implementations, provided the connected equipment, cable, and protocol support that throughput. For implementation, place the 0.1 µF charge-pump capacitors close to their designated pins and route RS-232 traces away from sensitive analog and clock signals. Confirm every unused input and output state, especially when placing the part between systems with different logic voltage levels. Do not infer an unqualified alternative from functional similarity; a true drop-in replacement must match the 18-pin footprint and pin functions. This page combines verified Analog Devices product information, distributor identification, sourcing links, and design-oriented RS-232 considerations. It distinguishes documented values from unavailable specifications and does not treat general functional equivalents as guaranteed pin-to-pin replacements.

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

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.

ADM2561EBRNZ-RL7 - 3kV Isolated RS-485/RS-422 Transceiver | ADI

The Analog Devices ADM2561EBRNZ-RL7 is a 3 kV RMS signal- and power-isolated RS-485/RS-422 transceiver integrated in a 28-pin SOIC-W-FP (wide-body SOIC with fine pitch and exposed pad) package. 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.

ADM2563EBRNZ

ADM2563EBRNZ - 3 kV Isolated RS-485 Transceiver, 28-SOIC-W-FP | Analog Devices

The Analog Devices ADM2563EBRNZ is a 3 kV RMS signal and power isolated RS-485 transceiver integrated in a 28-pin SOIC-W-FP wide-body package with an integrated isoPower DC-to-DC converter. It supports full-duplex RS-422/RS-485 communication, ±15 kV IEC ESD protection on the bus pins, and complies with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987 (E). The device operates over a 3.0 V to 5.5 V VCC supply range with a 1.7 V to 5.5 V logic-side VIO rail. An isolated RS-485 transceiver is a transceiver whose logic-side UART interface and bus-side differential line driver/receiver are galvanically separated by an internal transformer-based isolation barrier, while a built-in isolated DC-DC converter delivers power across that same barrier. The ADM2563E family belongs to the RS-485 transceiver -> serial interface IC -> interface IC category within power management and signal-chain semiconductors, replacing discrete opto-couplers, transformers, and external isolated supplies with a single chip. 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.

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.

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.

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.

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.

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.

ADM3072EARZ - 3.3V Half-Duplex RS-485/RS-422 Transceiver, 15kV ESD | Analog Devices

The Analog Devices ADM3072EARZ is a 3.3 V, low-power, half-duplex RS-485/RS-422 transceiver with ±15 kV ESD protection, supplied in an 8-pin SOIC_N (SO-8) package. 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.

The Analog Devices ADM3202ARNZ is a low-power, 2-driver/2-receiver RS-232 line transceiver that operates from a single +3.3 V supply, supports data rates up to 460 kbps, and uses four external 0.1 uF charge pump capacitors, housed in a 16-lead SOIC_N (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) into the wider voltage swings specified by the EIA-232E and CCITT V.28 standards, and vice versa. Within the signal chain hierarchy, it belongs to the transceiver class of drivers/receivers under Interface ICs, bridging microcontrollers, processors, or UARTs to legacy serial ports, industrial equipment, and point-of-sale hardware. Key features include single-supply 3.3 V operation with an on-chip charge pump voltage doubler/inverter, conformance to EIA-232E and V.28 specifications, high-speed operation up to 460 kbps, and small 0.1 uF external charge pump capacitors that reduce board area and bill-of-materials cost compared to older parts requiring 1 uF or larger capacitors. Technically, the ADM3202 integrates two charge pump stages (doubler and inverter) to generate approximately +/-6 V RS-232 rails from the 3.3 V supply. The drivers deliver guaranteed EIA-232E output levels, and the receivers include internal input pull-ups so that unconnected receiver inputs default to a known mark state. The ADM3202 variant has no shutdown pin; the related ADM3222 and ADM1385 add a low-power shutdown facility for battery applications. Typical applications include industrial equipment serial ports, embedded systems with RS-232 debug or console links, point-of-sale terminals, battery-powered portable instrumentation (with ADM3222 variants), and any 3.3 V microcontroller design interfacing to legacy RS-232 equipment. Design considerations: place the four 0.1 uF charge pump capacitors as close as possible to the device pins and observe datasheet polarity for the flying capacitors; ensure the supply can support the transient charge pump current during data transmission. This page synthesizes distributor pricing, drop-in alternatives, pinout, and practical design notes not found in a single manufacturer datasheet, as of 2026-09-13.
