SN55LBC175
description
The SN55LBC175 is a monolithic quadruple differential line receiver with 3-state outputs and is designed to meet the requirements of the EIA Standards RS-422-A, RS-423-A, RS-485, and CCITT V.11. This device is 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 m V over a mon-mode input voltage range of 12 V to
- 7 V. Fail-safe design ensures that if the inputs are open-circuited, the outputs are always high. This device is designed using the Texas Instruments proprietary Lin Bi CMOS™ technology allowing low power consumption, high switching speeds, and robustness.
