SN75176ADR IC Transceiver Half 1/1 8SOIC - High Quality Industrial Electronic Component

So you’ve got a noisy industrial floor, long cable runs, or a system where motors start and stop unpredictably — that bus the PLC uses for control keeps dropping bits or getting errors, and a solid, reliabel transceiver that can handle the ±15kV ESD spikes and the common-mode voltage swings without hiccuping is what you actually need.

What this little SN75176ADR in the 8SOIC package does is take the incoming differential signals and turn them into clean single-ended data for your logic side, all while driving the line hard enough at 60mA to keep the bus alive over 100 feet or so of twisted pair.

1. 4.5V to 5.5V supply, but most buyers stick with the standerd 5V rail, and 10Mbps is the rated cap — plenty for your Modbus RTU or Profibus at 9600 baud where the real limit is scan cycle anyway.

The half-duplex part basically means you’re sharing a single pair of wires for send and receive, which the software (or a handshake pin) coordinates — and the -40°C to +85°C range means it’ll sit happily in a warm cabinet or out in a cold barn near the conveyor.

We usually have these in stock for about a 10-day lead or so on orders under 50 pieces, but if you need a couple hundred, just check — teh fab runs them in batches, and the dispenser reel packaging makes them a breeze for pick-and-place.

One thing people don’t always think to ask is that the 5V tolerant digital inputs mean you can hang this directly off a 3.3V controller’s UART without a level shifter, as long as you respect the data rate limits — actually, we’ve seen them work at 5Mbps just fine in that scenario.
