description
The SN65LBC175 and SN75LBC175 are monolithic, quadruple, differential line receivers with 3-state outputs
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 LinBiCMOStechnology 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 is available in the 16-pin DIP (N), small-outline package (D), and the wide
small-outline package (DW). The SN75LBC175 is available in the 16-pin DIP (N) and the small-outline package
(D).
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.
