Integrated Circuit
Quad EIA−422 Line Receiver
With Three−State Outputs
Description:
The NTE7174 is a Quad EIA−422/3 Receiver in a 16−Lead DIP type package that features four inde-
pendent receiver chains which comply with EIA Standards for the Electrical Characteristics of Bal-
anced/Unbalanced Voltage Digital Interface Circuits. The Receiver outputs are 74LS compatible,
three−state structures which are forced to a high impedence state when the appropriate output control
pin reaches a logic zero condition. A PNP device buffers each output pin to assure minimum loading
for either logic one or logic zero inputs. In addition, each receiver chain has internal hysteresis circuitry
to improve noise margain and discourage output instability for slowly changing input waveforms.
