SN65LBC173D Description

Short technical summary and product information.

The SN65LBC173D from Texas Instruments is a monolithic quadruple differential line receiver featuring 3-state outputs. It is engineered to meet the stringent requirements of ANSI standards EIA/TIA-422-B, EIA/TIA-423-B, RS-485, and ITU Recommendations V.10 and V.11.

 

Optimized for balanced multipoint bus transmission, this receiver supports data rates up to and exceeding 10 million bits per second. Key electrical characteristics include an input sensitivity of ±200 mV and a low-power consumption of 20 mA maximum. The device also incorporates an open-circuit fail-safe design for enhanced reliability.

 

Designed for operation in noisy environments and over long bus lines, the SN65LBC173D features input hysteresis for improved noise immunity. Its pulse duration capability is as short as 20 ns. The receivers share two ORed enable inputs, one active high and the other active low, providing flexible control.

 

Packaged in a 16-pin SOIC (D) surface-mount package, the SN65LBC173D operates within a temperature range of -40°C to 85°C. It is pin-compatible with older devices like the SN75173 and AM26LS32, offering a potential upgrade path.
