ADM213ARS

Overview

The ADM213ARS is a CMOS RS-232 transceiver operating from a single +5 V supply. It integrates four drivers and five receivers with an active-low shutdown control and active-high receiver enable. The device supports data rates up to 120 kB/s and generates ±10 V internally using external capacitors ranging from 0.1 μF to 10 μF. It operates within a temperature range of -40°C to +85°C in a 28-lead SSOP package.

Feature Summary

• Integrates onboard DC-to-DC converters for single-supply operation
• Features low power shutdown mode reducing consumption below 5 μW
• Maintains two receiver outputs active during shutdown state
• Includes Schmitt-trigger inputs for noise immunity

Applications

• Battery-powered equipment
• Laptop computers
• Printers and peripherals
• Modems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and compliance status. Ensure the component matches the required industrial temperature range and pin configuration before integration into the design.

Selection Notes

Select this model when a single +5 V supply is available and low power consumption is critical. The unique feature of maintaining two active receivers during shutdown makes it suitable for applications requiring ring indicator monitoring while the system is powered down.

Part Context

This component belongs to the ADM2xx family of line drivers and receivers designed for EIA-232-E and V.28 interfaces. It serves as a direct upgrade to older MAX2xxE series devices, offering improved performance and lower power dissipation while maintaining pin compatibility.

Replacement Considerations

The datasheet identifies the ADM213ARSZ as a RoHS-compliant version of the same functional part number.
