Overview
The MAX3232CSE+T is a low-power, true RS-232 transceiver designed by Maxim Integrated, now a part of Analog Devices Inc. This device is packaged in a 16-pin NSOIC and is notable for its ability to operate from a single supply voltage ranging from 3.0V to 5.5V. It features a proprietary low-dropout transmitter output stage and a dual charge pump, enabling it to maintain true RS-232 performance across this voltage range. The transceiver includes two RS-232 drivers and two RS-232 receivers, making it suitable for a variety of communication and interface applications.
