ADM202EAN - Dual RS-232 Driver/Receiver, 5V, 16-PDIP | Analog Devices
N.º de pieza: ADM202EAN ✓ ActivoADM202EAN Descripción general
An RS-232 transceiver is an interface IC that converts logic-level signals from a controller or terminal into bipolar RS-232 voltages and converts received RS-232 levels back into CMOS-compatible logic. Within the signal-chain hierarchy, the ADM202EAN belongs to the RS-232 interface transceiver category and connects UART-based digital systems to unipolar, single-ended communications ports using differential bipolar signaling.
Key features include compliance with the TIA/EIA-232-E and V.28 specifications, 230 kbit/s operation, and electromagnetic-immunity provisions covering the EU 89/336/EEC EMC Directive. ESD protection is specified at 8 kV contact discharge, 15 kV air-gap discharge, and 15 kV human-body-model levels. Fast transient burst immunity is referenced to IEC 61000-4-4, while low EMI emissions are referenced to EN 55022.
The ADM202E family provides a pin-compatible upgrade path for existing ADM202, ADM232L, MAX202E, and MAX232E sockets. Its charge-pump architecture eliminates the need for a separate external 5 V-to-±10 V converter, reducing board area and component count. The 230 kbit/s capability is appropriate for industrial equipment, data-acquisition systems, point-of-sale terminals, and legacy serial-control interfaces.
For layout, the charge-pump capacitors must be placed close to their associated pins, and the interface ground must connect to the equipment chassis through the strategy specified by the application EMC standard. Cable routing and enclosure grounding often determine real-world ESD and EFT performance more than the IC rating alone.
This page combines manufacturer specifications, verified distributor availability information, drop-in socket-compatibility candidates, and practical interface-design guidance to support component selection and PCB implementation.

Aplicaciones típicas
ADM202EAN es adecuado para 6 aplicacións: Industrial Serial Port Interface, Data-Acquisition and Test Equipment, Point-of-Sale and Retail Terminal, Legacy Controller and Peripheral Upgrade, Industrial Control Panel, Communications and Network Management Console.
Industrial Serial Port Interface
The ADM202EAN fits industrial controller and data-acquisition equipment that retains an RS-232 port but must operate from a single 5 V rail. Its documented 230 kbit/s maximum rate provides ample margin for command and telemetry traffic, while the on-chip charge pump reduces the external supply circuitry to capacitors as small as 0.1 µF. The 16-pin PDIP footprint also supports legacy control boards with through-hole sockets. Because industrial ports are exposed to cable-borne transients, the documented 8 kV contact and 15 kV air-gap ESD ratings should be combined with chassis grounding and appropriately selected external surge protection.
Recomendado
Data-Acquisition and Test Equipment
The ADM202EAN is appropriate for laboratory instruments and automated test systems that need a robust legacy serial-control channel. Operation up to 230 kbit/s supports faster command transfer than many slow RS-232 control ports, and the single 5 V supply simplifies internal power planning. TIA/EIA-232-E and V.28 compliance provides a defined interface baseline for legacy equipment. Designers should keep charge-pump loop routing compact, provide the datasheet-specified capacitor types and voltage ratings, and verify that bench-side cables connect chassis ground in a way that does not create additional ground-current paths.
Recomendado
Point-of-Sale and Retail Terminal
The ADM202EAN can serve legacy point-of-sale terminals, receipt peripherals, and service consoles that communicate over RS-232. Its 2-channel driver/receiver arrangement allows bidirectional control without a separate line-driver IC, and the 16-pin PDIP package supports repair-friendly through-hole assemblies. The single 5 V supply reduces external power-tree complexity, while the 230 kbit/s capability comfortably covers peripheral traffic. In retail equipment installed near mains-powered systems, engineers should retain the verified ESD and transient-immunity ratings while confirming that the enclosure, cable shield, and protective earth follow the applicable product-emissions standard.
Recomendado
Legacy Controller and Peripheral Upgrade
The ADM202EAN is well suited to upgrading an older controller or peripheral board where a 16-pin PDIP RS-232 socket must be retained. Analog Devices identifies the ADM202E family as a pin-compatible upgrade for ADM202, ADM232L, MAX202E, and MAX232E sockets, allowing mechanical reuse while adding a documented robust ESD and EMC feature set. Before substituting, compare the exact charge-pump capacitor values and ensure that any receiver fail-state or enable differences will not alter firmware behavior. The 0.1 µF-capable charge pump helps limit board area on already crowded legacy boards.
Recomendado
Industrial Control Panel
The ADM202EAN can interface service ports or configuration connectors on industrial control panels, where a wired RS-232 service channel is easier to field-support than a wireless link. The dual-channel implementation supports both transmit and receive paths, while the 5 V-only supply requirement simplifies connection to control-panel rails. Documented ESD protection of 8 kV contact and 15 kV air gap supports robust service-port use, provided the connector and enclosure implement equivalent precautions. Keep the interface ground and cable shield referenced according to the manufacturer’s EMC guidance, and confirm the operating-temperature grade against the verified data before final release.
Recomendado
Communications and Network Management Console
The ADM202EAN is suitable for network-management and communications equipment that retains an RS-232 console for configuration, logging, or out-of-band access. A 230 kbit/s interface rate provides sufficient bandwidth for console traffic, and the single 5 V supply is convenient in multi-rail communications hardware. Its documented EMC and ESD immunity features help designers meet real-world installation conditions, but the interface still requires a controlled chassis and cable strategy. The 16-pin PDIP package favors serviceable legacy and industrial designs; compact new platforms may prefer a surface-mount transceiver after confirming electrical and pin compatibility.

Notas de diseño
Place the charge-pump capacitors as close as practical to the ADM202EAN pins identified in the manufacturer data sheet, and keep the associated traces short to limit switching-current loops. Although the charge pump operates from 0.1 µF-capable capacitors, using the exact manufacturer-recommended capacitance, dielectric class, and voltage rating is important for reliable startup and low EMI. Do not substitute the generic MAX232 capacitor arrangement without verifying the ADM202E pin functions and recommended values.
An IC-level ESD rating does not by itself guarantee system compliance. Connect the interface ground to chassis or protective earth using the grounding architecture specified by the applicable product standard, and use a shielded cable with a chassis-referenced connector shell where the RS-232 port is externally accessible. The verified 8 kV contact and 15 kV air-gap ESD levels should be confirmed in the assembled equipment, since connector selection, cable length, and grounding topology materially affect the result.
Do not assume that any device described as an RS-232 transceiver is automatically drop-in replaceable. The ADM202EAN is a 16-pin PDIP part with a specific charge-pump connection arrangement. Before substituting MAX202EPE or MAX232EPE, compare the numbered pinout, external capacitor values and types, V+ and V- connections, receiver outputs, and supply decoupling. Also check whether the original board relies on receiver fail-state behavior that could change the interpretation of a disconnected or shorted cable.
