Check for Samples: DS3486 FEATURES 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. 1 2 Four Independent Receivers
