ADM213ARZ

Overview

The ADM213ARZ is a CMOS RS-232 transceiver designed for EIA-232-E and V.28 communication interfaces, operating from a single +5 V supply. It integrates four drivers and five receivers with internal charge pump voltage converters that generate ±10 V levels. The device supports data rates up to 120 kB/s and features low power shutdown mode consuming less than 5 μW. A unique characteristic of the ADM213 is that two receivers remain active during shutdown for ring indicator monitoring. It utilizes external capacitors ranging from 0.1 μF to 10 μF.

Feature Summary

• Integrates on-board DC-to-DC converters to operate from a single 5 V supply
• Features low power shutdown mode reducing consumption below 5 μW
• Maintains two receiver outputs in active state during shutdown for monitoring
• Includes Schmitt-trigger inputs with hysteresis for noise immunity

Applications

• Battery-powered equipment requiring low standby power
• Modems and printers utilizing standard serial interfaces
• Instruments and peripherals connected via RS-232 links
• Systems requiring ring indicator monitoring while powered down

Procurement Notes

Verify the specific package variant required, as the Z suffix indicates RoHS compliance. Confirm the ordering suffix matches the desired tape-and-reel or tube packaging configuration. Ensure the component meets the industrial temperature range specifications for the intended deployment environment.

Selection Notes

Select this part when a single 5 V supply is available but RS-232 voltage levels are needed. Choose the ADM213 over similar family members specifically if the ability to monitor two receiver lines during shutdown is necessary. Verify that the application requires four drivers and five receivers to match the pin count and functionality.

Part Context

This component belongs to the ADM2xx family of line drivers and receivers manufactured by Analog Devices. It serves as a direct upgrade to older MAX206-211/213 devices, offering improved power efficiency and integrated charge pumps. The series addresses applications where traditional dual-voltage supplies are unavailable or impractical.

Replacement Considerations

The datasheet confirms pin compatibility with MAX206, MAX207, MAX208, MAX211, and MAX213 devices. Substitution should be verified against the specific electrical requirements of the legacy design.
