Quadruple Low-Power Differential Line Receiver

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 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 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.
