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

Notes
LIFE SUPPORT POLICY
NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT
DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL
COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION. As used herein:
1. Life support devices or systems are devices or
systems which, (a) are intended for surgical implant
into the body, or (b) support or sustain life, and
whose failure to perform when properly used in
accordance with instructions for use provided in the
labeling, can be reasonably expected to result in a
significant injury to the user.
2. A critical component is any component of a life
support device or system whose failure to perform
can be reasonably expected to cause the failure of
the life support device or system, or to affect its
safety or effectiveness.
