MAX3238EAI+

The MAX3238EAI+ is a 1µA, up to 250Kbps, true RS232 transceiver with AutoShutdown Plus in 28 pin SSOP package. The 5 driver/3 receiver complete serial port is a 3V-powered EIA/TIA-232 and V.28/V.24 communications interface intended for notebook or subnotebook computer applications. A proprietary, high efficiency, dual charge-pump power supply and a low dropout transmitter combine to deliver true RS232 performance from a single supply. When device does not sense a valid signal transition on either the receiver or transmitter inputs within 30sec, the on-board power supply and drivers shut down. This occurs if the RS232 cable is disconnected or if transmitters of the connected peripheral are inactive. The system turns on again when a valid transition is applied to any RS232 receiver or transmitter input, saving power without changes to the existing BIOS or operating system.
