MAX3232 Datasheet PDF – True RS-232 Transceiver – Maxim

Part Number: MAX3232, MAX3232ESE

Function: 3.0V to 5.5V / up to 1Mbps / True RS-232 Transceiver

Package: 16 Narrow SO, 16 TSSOP, 16 DIP Type

Manufacturer: Maxim




The 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 charge-pump 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.

The deives have 2 receivers and 2 drivers. The MAX3222 features a 1µA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1µA supply current. The ICs are pin, package, and functionally compatible with the industry-standard MAX242 and MAX232, respectively.
