LTC1338 - 5V Low Power RS232 5-Driver/3-Receiver Transceiver - Linear Technology（凌力尔特）
功能描述
The LTC1338 is a 5-driver/3-receiver RS232 transceiver with very low supply current. In the no load condition, the supply current is only 500µA. The charge pump only requires four 0.1µF capacitors.
In SHUTDOWN mode, the supply current is further reduced to 0.2µA. In RECEIVER ALIVE mode, all three receivers are kept alive and the supply current is 50µA. All RS232 outputs assume a high impedance state in SHUTDOWN and with the power off.
The LTC1338 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 120k baud with a 2500pF, 3kohms load. Both driver outputs and receiver inputs can be forced to ?25V without damage, and can survive multiple ±10kV ESD strikes.
