MAX3243EUI+T Description

Short technical summary and product information.

The MAX3243EUI+T from Analog Devices (formerly Maxim Integrated) is a versatile RS-232 transceiver designed for efficient operation in battery-powered and hand-held equipment. This device features 3 drivers and 5 receivers, supporting full-duplex communication.

 

Key electrical characteristics include a wide operating voltage range of 3V to 5.5V and a data rate of 120Kbps. A notable feature is the AutoShutdown function, which reduces supply current to as low as 1µA when no valid signal is detected on the receiver inputs, conserving power during idle periods. The device requires minimal external components, needing only 0.1µF capacitors for 3.3V operation.

 

Packaged in a 28-TSSOP, the MAX3243EUI+T is suitable for surface-mount applications. Its design simplifies power requirements by eliminating the need for a ±12V supply, making it ideal for portable diagnostics equipment and other peripherals where space and power efficiency are critical.
