LTC1346A

10Mbps DCE/DTE

V.35 Transceiver

DESCRIPTIO

EATURE

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

forthecontrolsignals,theLTC1346Aformsacompletelow

power DTE or DCE V.35 interface port.

■

Single Chip Provides Complete Differential Signal

Interface for V.35 Port

Drivers and Receivers Will Withstand Repeated

±10kV ESD Pulses

10Mbaud Transmission Rate

Meets CCITT V.35 Specification

Operates from ±5V Supplies

Shutdown Mode Reduces I_CCto Below 1µA

Selectable Transmitter and Receiver Configurations

Independent Driver/Receiver Enables

Transmitter Maintains High Impedance When

Disabled, Shut Down or with Power Off

Transmitters Are Short-Circuit Protected

■

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 1µA.

■

The LTC1346A transceiver operates up to 10Mbaud. All

transmittersfeatureshort-circuitprotection.Boththetrans-

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.
