DUAL DIFFERENTIAL LINE DRIVER
WITH 3-STATE OUTPUTS
SLLS088B – JANUARY 1977 – REVISED MAY 1995
D OR N PACKAGE
NC – No internal connection
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
The SN75159 is characterized for operation from 0°C to 70°C.
