MAX221EUE Description

Short technical summary and product information.

The MAX221EUE is a transceiver IC from Analog Devices, designed for EIA/TIA-232E and V.28/V.24 communications. It operates from a single +4.5V to +5.5V supply, eliminating the need for a bipolar ±12V supply due to its integrated charge pump circuitry.

 

This device supports full duplex communication with a data rate of 250kbps and features receiver hysteresis of 500mV. The operating temperature range is -40°C to +85°C.

 

The MAX221EUE is housed in a 16-TSSOP package, suitable for surface mounting. Its compact size and single-supply operation make it ideal for applications where board space and power efficiency are critical. The integrated charge pump and capacitors contribute to its space-saving design.

 

Key features include a 5μW shutdown mode for reduced power consumption. This transceiver is well-suited for interface translation, multidrop RS-232 networks, and portable diagnostic equipment.
