MAX3221EUE+ Description

Short technical summary and product information.

The MAX3221EUE+ is a single-chip, 3.3V/5V powered EIA/TIA-232 transceiver from Analog Devices / Maxim Integrated. It offers true RS-232 performance with low power consumption, featuring an AutoShutdown mode that reduces supply current to 1µA when receivers are inactive.

 

This transceiver supports a data rate of 250kbps and operates over a voltage range of 3V to 5.5V. It includes 1 driver and 1 receiver, with receiver hysteresis of 500mV to improve noise immunity. The device is designed for full-duplex communication.

 

Packaged in a 16-TSSOP (0.173", 4.40mm Width) with surface mount mounting type, the MAX3221EUE+ is suitable for applications requiring compact solutions. Its operating temperature range is -40°C to 85°C, making it robust for various environments. The AutoShutdown feature is particularly beneficial for battery-powered and hand-held equipment, conserving power when the RS-232 connection is idle or disconnected.
