DS3486
Quad RS-422, RS-423 Line Receiver
General Description
National’s quad RS-422, RS-423 receiver features four inde-
pendent receivers which comply with EIA Standards for the
electrical characteristics of balanced/unbalanced voltage
digital interface circuits. Receiver outputs are 74LS compat-
ible, TRI-STATE® structures which are forced to a high im-
pedance 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 inter-
nal hysteresis circuitry to improve noise margin and discour-
age output instability for slowly changing input waveforms.
Features
n Four independent receivers
n TRI-STATE outputs
n Internal hysteresis −140 mV (typ)
n Fast propagation times −19 ns (typ)
n TTL compatible outputs
n 5V supply
n Pin compatible and interchangeable with MC3486
