description
The SN75159 dual differential line driver with 3-state outputs is designed to provide all the features of the
SN75158 line driver with the added feature of driver output controls. There is an individual control for each driver.
When the output control is low, the associated outputs are in a high-impedance state and the outputs can neither
drive nor load the bus. This permits many devices to be connected together on the same transmission line for
party-line applications.
The SN75159 is characterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values except differential output voltage VOD are with respect to the network ground terminal. VOD is at the Y output with
respect to the Z output.
