description

The TL3695 differential bus transceiver is designed for bidirectional data communication on multipoint

bus-transmission lines. It is designed for balanced transmission lines and meets TIA/EIA-422-B,

TIA/EIA-485-A, and ITU Recommendation V.11.

The TL3695 combines a 3-state differential line driver and a differential input line receiver, both of which operate

from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively,

which can be externally connected together to function as a directional control. The driver differential outputs

and the receiver differential inputs are connected internally to form a differential input/output (I/O) bus port that

is designed to offer minimum loading to the bus when the driver is disabled or VCC = 0. This port features wide

positive and negative common-mode voltage ranges, making the device suitable for party line applications.

The TL3695 is characterized for operation from 0°C to 70°C.
