SN65LBC175DWR

The SN65LBC175 and SN75LBC175 are monolithic quadruple differential line receivers with three-state outputs, designed to meet the requirements of EIA standards RS-422-A, RS-423-A, RS-485, and CCITT Recommendation V.11. These devices are optimized for balanced multipoint bus transmission at data rates up to and exceeding 10 Mbps. The receivers are enabled in pairs using active-high enable inputs. Each differential receiver features high-impedance inputs, hysteresis for improved noise immunity, and ±200mV sensitivity over a common-mode input voltage range of −12V to −7V. Fail-safe design ensures the output remains in a high state when the inputs are open-circuited. Both devices are designed using TI's proprietary LinBiCMOS™ technology to achieve low power consumption, high switching speed, and robustness. These devices provide excellent performance when used with the SN75LBC172 or SN75LBC174 quadruple line drivers. The SN65LBC175 is available in 16-pin DIP (N), small-outline (D), and wide-body (DW) packages. The SN75LBC175 is available in 16-pin DIP (N) and small-outline (D) packages. The SN65LBC175 operates over an industrial temperature range of −40°C to 85°C. The SN75LBC175 operates over a commercial temperature range of 0°C to 70°C.
