Texas Instruments SN65176BDR RS422/RS485 Line Driver 5V SOIC-8

The Texas Instruments SN65176BDR RS422/RS485 Bus Transceiver is a differential bus transceiver operating from a single 5V supply (range 4.75V to 5.25V), housed in a compact 8-pin SOIC package.

It integrates a three-state differential line driver and a differential input line receiver for bidirectional data communication over multipoint bus lines. The driver and receiver feature active high and low enables, which can be tied together externally for straightforward direction control. Its differential I/O bus ports are designed to present minimal loading to the bus when disabled, helping to preserve overall network performance.

Key Features

• Wide positive and negative common-mode voltage range, suited to party-line applications
• Compliant with ANSI TIA/EIA-422-B, TIA/EIA-485-A, and ITU recommendations V.11 and X.27
• Driver output capability of ±60 mA maximum
• Thermal shutdown protection and driver current limiting
• Receiver input impedance of 12 kΩ minimum, sensitivity of ±200 mV, and 50 mV input hysteresis for improved noise immunity
• Operating temperature range from -40°C to 105°C
