SN65LBC173AD Description

Short technical summary and product information.

The SN65LBC173AD from Texas Instruments is a quadruple differential line receiver optimized for balanced multipoint bus communication. It is designed to meet TIA/EIA-485, TIA/EIA-422, and ISO 8482 standards, supporting data rates up to and exceeding 50 Mbps.

 

This receiver features a wide common-mode input range of -7V to 12V and fault protection from -10V to 15V, ensuring robust performance in challenging environments. It operates over a temperature range of -40°C to 85°C and requires a supply voltage between 4.75V and 5.25V. The device offers low standby power consumption, drawing less than 20µA.

 

Packaged in a 16-SOIC surface-mount form factor, the SN65LBC173AD is suitable for various industrial and communication systems. Its design includes fail-safe features for bus short-circuit, open-circuit, and idle-bus conditions, along with ESD protection exceeding 6 kV on bus inputs. It is pin-compatible with several older receiver ICs, facilitating upgrades.

 

Key electrical characteristics include 4 receivers, 0 transmitters, a signaling rate of 50Mbps, and receiver hysteresis of 40mV. The device is rated for 32 nodes on the bus.
