ADM1385ARS

Overview

The ADM1385ARS is a low-power, dual-channel RS-232 transceiver manufactured by Analog Devices Inc. Operating from a single 3.3 V supply, it supports data rates up to 460 kbps and meets EIA-232E specifications. The device features a complete shutdown mode that reduces quiescent current to less than 0.5 μA. It utilizes four external 0.1 μF charge pump capacitors for voltage conversion. The component is housed in a 20-lead SSOP package (RS-20) and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

Includes a driver disable mode and a complete shutdown mode for power management
Operates from a single 3.3 V power supply using internal charge pumps
Features Schmitt-trigger receiver inputs with hysteresis for noise immunity
Pin-compatible with the LTC1385 CG

Applications

General-purpose RS-232 data links
Portable instruments
Printers, palmtop computers, and PDAs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. Ensure the procurement channel provides valid traceability for the RS-20 package variant. Cross-reference the part number with the latest datasheet revision to confirm availability of the ADM1385ARS model specifically.

Selection Notes

Select this component when a low-power RS-232 interface is required for battery-operated devices. The ADM1385ARS is suitable for applications needing a driver disable mode alongside full shutdown capabilities. It serves as an upgrade for MAX3222/MAX3232 and LTC1385 designs requiring 3.3 V operation.

Part Context

The ADM1385ARS belongs to the ADM3202/ADM3222/ADM1385 family of high-speed RS-232/V.28 interface devices. These transceivers are CMOS-based modifications of the AD230 to AD241 family, offering plug-in compatibility without materially different applications. The series is designed to minimize power dissipation for maximum battery life in portable systems.

Replacement Considerations

The datasheet identifies the ADM1385ARS as an upgrade for the MAX3222, MAX3232, and LTC1385. Verify pinout compatibility, particularly regarding the DD and SD pins, before substituting these parts.
