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, andCCITTRecommendation
V.11. The devices are optimized for balanced
multipointbustransmissionatdataratesuptoand
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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to GND.
2. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input.
