Product details

Drop-in replacement for SN75176BDR — what changed

The SN75176BDRG4 is functionally and pin-compatible with the older SN75176BDR. The 'G4' suffix indicates a RoHS-compliant, halogen-free version of the same die in the same 8-SOIC footprint. If your existing BOM uses the SN75176BDR, this part swaps in without a board spin — just verify the supply decoupling and bus termination are already to the 5 V ±5% spec.

5 V supply and commercial temperature — the hard constraints

If your system has moved to a 3.3 V backplane, look at the SN65HVD or ISO35xx families instead. For motor drives, outdoor sensors, or engine-bay modules, you need the industrial-temperature variant (SN75176BDR).

Frequently asked questions

Can SN75176BDRG4 be used as a drop-in replacement for SN75176BDR?

Yes. The SN75176BDRG4 is pin-compatible and functionally identical to the SN75176BDR. The 'G4' suffix denotes RoHS and halogen-free compliance. No board layout change is needed.

Is SN75176BDRG4 compatible with RS-232?

No. The SN75176BDRG4 is an RS-422/RS-485 transceiver. RS-232 uses different voltage levels and signaling — this part is not compatible with RS-232 interfaces.
