MAX3243IPW Transceiver: Pinout,Specification, and Datasheet

When the MAX3243 does not sense a valid signal level on their receiver inputs, the onboard power supply and drivers shut down. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripherals are turned off. The system turns on again when a valid level is applied to any RS-232 receiver input. 

The MAX3243 requires only 0.1µF capacitors in 3.3V operation, and can operate from input voltages ranging from +3.0V to +5.5V. 

A proprietary, high-efficiency, dual charge-pump power supply and a low-dropout transmitter combine to deliver true RS-232 performance from a single +3.0V to +5.5V supply. 

The MAX3243 is a 3-driver/5-receiver with a complementary always-active receiver for external monitoring in a variety of 28 pin packages. See Order Information table for package offerings.
