SN75LV4737ADBR

IC, RS-232 TRANSCEIVER, 5.5V, SSOP-28.

The SN75LV4737ADBR is a RS-232 multichannel Line Driver/Receiver consists of three line drivers, five line receivers and a charge-pump circuit. It provides the electrical interface between an asynchronous communication controller and the serial-port connector and meets the requirements of TIA/EIA-232-F. This combination of driver and receiver matches those needed for the typical serial port used in an IBM PC/AT or compatibles. The charge pump and five small external capacitors allow operation from a single 3.3V supply and four capacitors allow operation from a 5V supply. The device has flexible control options for power management when the serial port is inactive. A common disable for all of the driver and receiver is provided with the active-high STBY input. The active-low EN input is an enable for one receiver to implement a wake-up feature for the serial port.
