description
The SN65LBC175 and SN75LBC175 are
monolithic, quadruple, differential line receivers
with 3-state outputs and are designed to meet the
requirements of the EIA standards RS-422-A,
RS-423-A, RS-485, and CCITT Recommendation
V.11. The devices are optimized for balanced
multipoint bus transmission at data rates up to and
exceeding 10 million bits per second. The
receivers are enabled in pairs, with an active-high
enable input. Each differential receiver input
features high impedance, hysteresis for
increased noise immunity, and sensitivity of
± 200 mV over a common-mode input voltage
range of 12 V to –7 V. The fail-safe design ensures
that when the inputs are open-circuited, the
outputs are always high. Both devices are
designed using the TI proprietary LinBiCMOS™
technology allowing low power consumption, high
switching speeds, and robustness.
These devices offer optimum performance when
used with the SN75LBC172 or SN75LBC174
quadruple line drivers. The SN65LBC175 and
SN75LBC175 are available in the 16-pin DIP (N)
and small-outline inline circuit (SOIC) D
packages.
The SN65LBC175 is characterized over the
industrial temperature range of – 40°C to 85°C.
The SN75LBC175 is characterized for operation
over the commercial temperature range of 0°C
to 70°C.
