LTC1346A  
10Mbps DCE/DTE  
V.35 Transceiver  
U
DESCRIPTIO  
EATURE  
S
F
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 ICC to 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.
