The SN75179BP is a single-channel, full-duplex transceiver supporting both RS-422 and RS-485 protocols. It integrates one differential driver and one differential receiver in an 8-pin DIP package. Full-duplex operation means the driver and receiver are active simultaneously, using separate twisted pairs for transmit and receive. This is the right choice for point-to-point links where bidirectional traffic flows without bus turnaround delays. Supply voltage is 4.75 V to 5.25 V — a single 5 V rail. The 50 mV receiver hysteresis filters noise on long cable runs, reducing the chance of false edge triggers on the RX line.
Temperature grade and package — commercial, through-hole, breadboard-friendly
It is suited for indoor equipment, lab instruments, and office automation — not for engine bays, outdoor telecom cabinets, or factory-floor enclosures without climate control. The 8-DIP (0.300", 7.62 mm) through-hole package is breadboard- and protoboard-friendly. It is also easier to hand-solder and rework than a surface-mount SOIC, which matters for low-volume builds and repair scenarios.
