Integrated Circuit
Quad EIA−422 Line Driver
With Three−State Outputs
Description:
The NTE7175 is a Quad EIA−422 Driver in a 16−Lead DIP type package that features four indepen-
dent driver chains which comply with EIA Standards for the Electrical Characteristics of Balanced
Voltage Digital Interface Circuits. The outputs are three−state structures which are forced to a high
impedence state when the appropriate output control pin reaches a logic zero condition. All input pins
are PNP buffered to minimize input loading for either logic one or logic zero inputs. In addition, internal
circuitry assures a high impedance output state during the transition between power up and power
down.
Features:
D Four Independent Driver Chains
D Three−State Outputs
D PNP High Impedence Inputs (PIA Compaitible)
D Fast Propagation Times (Typ 15ns)
D TTL Compaitible
D Single 5V Supply Voltage
D Output Rise and Fall Times Less Than 20ns
