MAX3232ESE+T

3.0V to 5.5V, Low-Power, up to 1Mbps, True RS-232  Transceivers Using Four 0.1μF External Capacitors

RS-232接口集成电路 3-5.5V 235kbps Transceiver

General Description

The MAX3232ESE+T MAX3222/MAX3232/MAX3237/MAX3241 transceivers have a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. The devices require only four small 0.1μF external chargepump capacitors. The MAX3222, MAX3232, and MAX3241 are guaranteed to run at data rates of 120kbps while maintaining RS-232 output levels. The MAX3237 is guaranteed to run at data rates of 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode, while maintaining RS-232 output levels.
