Description

The LTC1346A is a single chip transceiver that providesthe differential clock and data signals for a V.35 interface from ±5V supplies. Combined with an external resistortermination network and an LT®1134A RS232 transceiver
for the control signals, the LTC1346A forms a complete lowpower DTE or DCE V.35 interface port.

The LTC1346A features three current output differentialtransmitters and three differential receivers. The trans-ceiver can be configured for DTE or DCE operation orshutdown using three Select pins. In the shutdown mode,
the supply current is reduced to below 1µA.

The LTC1346A transceiver operates up to 10Mbaud. Alltransmitters feature short-circuit protection. Both the trans-
mitter outputs and the receiver outputs can be forced intoa high impedance state. The transmitter outputs and re-
ceiver inputs feature ±10kV ESD protection.
