description

The LTC®1345 is a monolithic transceiver that uses a single 5V supply to provide differential clock and data signals to the V.35 interface. Paired with an external resistor termination network and an LT®1134A RS232 transceiver that controls the signal, LTC1345 forms a complete low-power DTE or DCE V.35 interface port with a single 5V operating supply.

 LTC1345 has three current output differential transmitters, three differential receivers, and a charge pump. The transceiver can be configured for DTE or DCE operation, or shut down with two selector pins. In shutdown mode, the supply current is reduced to 1μA.

 The transceiver can operate up to 10M baud. All transmitters are short-circuit protected, and a receiver output enable pin allows the receiver output to be forced into a high-impedance state. Both the transmitter output and receiver input are ±10kV ESD protected. The charge pump stabilizes one VEE output by employing three external 1μF capacitors.
