ADM213EARZ-REEL

Overview

The ADM213EARZ-REEL is an RS-232 line transceiver from Analog Devices, operating on a single 5 V supply. It features four drivers and five receivers with a guaranteed data rate of 230 kbps. The device includes shutdown and enable control pins; in shutdown mode, the charge pump and three receivers are disabled while two receivers remain active for peripheral monitoring. It provides ±15 kV ESD protection and complies with EMC directives. The component utilizes internal TTL/CMOS inputs with pull-up resistors and RS-232 inputs with pull-down resistors. It requires four external 0.1 μF capacitors for the charge pump and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Complies with EU EMC directive (89/336/EEC) with low EMI emissions
• Provides robust ESD protection up to ±15 kV on all I/O lines
• Features shutdown mode that disables the charge pump and most receivers while keeping two receivers active
• Operates from a single 5 V power supply using only four external capacitors

Applications

• Laptop computers
• Notebook computers
• Printers
• Peripherals
• Modems

Procurement Notes

Verify the specific package variant against the datasheet ordering guide, as the REEL suffix indicates tape-and-reel packaging but does not specify the physical footprint. Confirm the presence of the SHDN and EN pins matches the ADM213E truth table requirements for your system design. Ensure the voltage supply remains within the 4.5 V to 5.5 V range for optimal performance.

Selection Notes

Select this component when high ESD immunity and EMC compliance are required for RS-232 interfaces. The ADM213E is distinct from the ADM211E due to its unique shutdown behavior where two receivers remain active. Verify that the 230 kbps data rate meets the application's speed requirements and that the 28-pin package fits the PCB layout constraints.

Part Context

The ADM213E belongs to the ADM2xxE family of ruggedized RS-232 transceivers designed for harsh electrical environments. This family offers backward compatibility with earlier ADM2xx products, facilitating easy upgrades. The ADM213E specifically differentiates itself by allowing receiver monitoring during shutdown, making it suitable for battery-operated systems requiring peripheral wake-up capabilities.

Replacement Considerations

The ADM211E is a related model within the same family but lacks the active receiver feature during shutdown. Other models like the ADM206E, ADM207E, and ADM208E offer different driver/receiver counts and pin configurations. Direct substitution requires verifying pin compatibility and functional differences in shutdown modes.
