DS3486N DIP IC

General Description
National?s 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.
