DESCRIPTION

Texas Instruments' quad RS-422, RS-423 receiver

features four independent receivers which comply

with EIA Standards for the electrical characteristics of

balanced/unbalanced voltage digital interface circuits.

Receiver outputs are 74LS compatible, TRI-STATE

structures which are forced to a high impedance state when the appropriate output control pin reaches a

logic zero condition. A PNP device buffers each

output control pin to assure minimum loading for

either logic one or logic zero inputs. In addition, each

receiver has internal hysteresis circuitry to improve

noise margin and discourage output instability for

slowly changing input waveforms.
