Part Number : MAX3238CAI
Function : +3.0V to +5.5V, 10nA, 250kbps RS-232 Transceiver
Package : SSOP 28 Pin type
Maker : Maxim Integrated
Pinouts : 
Description :
The MAX3238CAI, MAX3238 true RS-232 transceiver achieves a 1µA supply current with Maxim’s revolutionary AutoShutdown Plus™ feature. When the 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 RS-232 cable is disconnected or if the transmitters of the connected peripheral are inactive. The system turns on again when a valid transition is applied to any RS-232 receiver or transmitter input, saving power without changes to the existing BIOS or operating system.
