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.
