It integrates one differential driver and one differential receiver in an 8-SOIC package, operating from a 4.75V to 5.25V supply rail.
This part is strictly a 5V device. If your board runs a 3.3V bus, the SN65176BDRE4 will not meet the input thresholds — you need the 3.3V-rated SN65HVD3082E or similar.
TI lists the SN65176BDRE4 as Active.
The two parts are electrically identical — same RS-485/RS-422 half-duplex transceiver, same 5V supply, same –40°C to 105°C range. The only difference is the packaging and reel quantity: the '' suffix on SN65176BDRE4 designates a specific tape-and-reel configuration (typically 2500 units per reel for 8-SOIC), while SN65176BDR may ship in a different reel format or tube. Both are active and interchangeable in the same PCB footprint.
Yes, the SN65176BDRE4 is a direct functional replacement for the SN75176B in most RS-485 designs. Both are 5V half-duplex transceivers with 1 driver and 1 receiver in an 8-pin SOIC footprint. Verify the pinout matches your layout — both use the standard 8-SOIC RS-485 pin arrangement (RO, RE, DE, DI, GND, A, B, VCC).
