The SN75176 is a 5 V half-duplex RS-485/RS-422 differential bus transceiver for industrial and embedded communication, drawing very low quiescent current.
Product Overview
The SN75176 describes the classic 5 V RS-485 transceiver standard and is pin-compatible with the industry-standard 75176 family. It integrates one driver and one receiver with independent enable control, enabling multidrop differential-bus links for PLCs, factory automation, and industrial networks running on 5 V logic.
Newfly supplies verified, RoHS-compliant SN75176-class transceivers with cross-reference and BOM-matching support for production sourcing.

FAQ
Q: Is the SN75176 a 5 V or 3.3 V device?
A: The SN75176 operates from 5 V. For a 3.3 V RS-485 transceiver, consider the SP3485 or MAX3485 families.
Q: How many nodes can share the bus?
A: Up to 32 unit-load transceivers on a single RS-485 bus; confirm your node’s unit load with the datasheet.
Q: Can you provide a cross-reference?
A: Yes. Share your BOM and Newfly will suggest compatible 5 V RS-485 alternatives.
