ADM213ARZ-REEL

Overview

The ADM213ARZ-REEL is a CMOS RS-232 transceiver from the ADM2xx family, designed for EIA-232-E and V.28 interfaces using a single +5 V supply. It integrates four drivers and five receivers with on-board DC-to-DC converters that generate ±10 V levels from the 5 V input. The device supports data rates up to 120 kB/s and features low power consumption of 15 mW in normal operation. A shutdown mode reduces current draw to less than 5 μA. Two receivers remain active during shutdown for ring indicator monitoring.

Feature Summary

• Integrates internal charge pump voltage converters to operate from a single 5 V supply without external high-voltage sources.
• Features a low-power shutdown mode that disables the charge pump and most outputs while keeping two specific receivers active.
• Includes Schmitt-trigger inputs on receivers to ensure noise immunity and error-free reception with slow transition times.
• Provides an enable function to place receiver outputs in a high impedance state for microprocessor bus sharing.

Applications

• Battery-powered equipment requiring low standby power
• Modems and printers utilizing RS-232 communication
• Computer peripherals and instruments

Procurement Notes

Verify the package option matches the required footprint, as the ADM213 series is available in SOIC_W and SSOP variants. Confirm RoHS compliance status based on the 'Z' suffix in the ordering guide. Ensure the reel packaging aligns with automated assembly requirements. Cross-reference the specific revision history to confirm pinout consistency with existing designs.

Selection Notes

Select this component when a single 5 V supply is available but RS-232 voltage levels are required. The ADM213 is distinct within the family due to its five receivers and the ability to keep two active during shutdown. Compare against ADM211 if fewer receivers are needed or if different shutdown logic polarity is preferred. Verify capacitor values match the 0.1 μF to 10 μF specification range.

Part Context

The ADM213ARZ-REEL belongs to the ADM2xx line of RS-232 drivers and receivers manufactured by Analog Devices. This family replaces older AD2xx parts and offers enhanced performance with lower power dissipation. The part is pin-compatible with MAX206-211/213 derivatives, facilitating direct upgrades in existing hardware designs without layout changes.

Replacement Considerations

ADM211ARZ-REEL serves as a functional substitute with identical packaging and electrical characteristics, except it lacks the two additional receivers that remain active during shutdown. Verify control signal polarity differences between the SD and EN pins when swapping these variants.
