The LTC

®1346A is a single chip transceiver that provides

the differential clock and data signals for a V.35 interface

from

±5V supplies. Combined with an external resistor

termination network and an LT

®1134A RS232 transceiver

for the control signals, the LTC1346A forms a complete low

power DTE or DCE V.35 interface port.

The LTC1346A features three current output differential

transmitters and three differential receivers. The trans-

ceiver can be configured for DTE or DCE operation or

shutdown using three Select pins. In the shutdown mode,

the supply current is reduced to below 1

µA.

The LTC1346A transceiver operates up to 10Mbaud. All

transmitters feature short-circuit protection. Both the trans-

mitter outputs and the receiver outputs can be forced into

a high impedance state. The transmitter outputs and re-

ceiver inputs feature

±10kV ESD protection.
