The MAX3221EUE is a single-chip, 3.0V to 5.5V powered EIA/TIA-232 transceiver from Analog Devices. It integrates a dual charge-pump power supply and a low-dropout transmitter, eliminating the need for a ±12V supply and simplifying power requirements. This device features Maxim's AutoShutdown™ technology, which reduces supply current to 1µA when no valid signal is detected on the receiver inputs, making it ideal for battery-powered and hand-held equipment.
Key electrical characteristics include a supply voltage range of 3V to 5.5V, a data rate of 250kbps, and a receiver hysteresis of 500mV. The MAX3221EUE is configured as 1 driver and 1 receiver, supporting full duplex communication.
This transceiver is supplied in a 16-TSSOP package, designed for surface mounting. Its operating temperature range is -40°C to 85°C (TA). The device requires minimal external components, needing only 0.1µF capacitors for 3.3V operation.
