ADM213ARS-REEL

Overview

The ADM213ARS-REEL is a CMOS RS-232 transceiver manufactured by Analog Devices Inc. It operates from a single +5 V supply and includes internal charge pumps to generate ±10 V for RS-232 signaling. The device features four drivers and five receivers, supporting data rates up to 120 kB/s. It incorporates an active-low shutdown pin and an active-high receiver enable pin. During shutdown, two receivers remain active for ring indicator monitoring. Power consumption is reduced to less than 5 μW in shutdown mode.

Feature Summary

• Integrates on-board DC-to-DC converters for single-supply operation
• Features low power shutdown mode with two active receivers
• Includes TTL/CMOS compatible inputs and outputs
• Provides Schmitt-trigger receivers for noise immunity

Applications

• Battery-powered equipment
• Modems
• Printers
• Instruments

Procurement Notes

Verify the ordering suffix REEL indicates tape-and-reel packaging. Confirm RoHS compliance status via the Z suffix if required. Ensure the SSOP package option matches the target PCB footprint. Validate the industrial temperature range specifications against system requirements.

Selection Notes

Select this component when a single 5 V supply is available without ±12 V rails. The ADM213 is suitable for applications requiring ring indicator monitoring during low-power states. Verify that the 120 kB/s data rate meets the communication speed requirements. Check compatibility with MAX206-211/213 pinouts if replacing legacy designs.

Part Context

The ADM213 is part of the ADM2xx family of line drivers and receivers designed for EIA-232-E and V.28 interfaces. This family eliminates the need for external voltage inverters or dual supplies. The ADM213 variant specifically adds receiver enable functionality and maintains two active receivers during shutdown.

Replacement Considerations

The datasheet notes pin compatibility with MAX206-211/213 devices. Verify electrical parameters and control logic polarities before substitution.
