Dual RS422/RS485 driver in an 8-pin DIP
The SN75158P is a dual-channel line driver from Texas Instruments' 75000 series, supporting both RS422 and RS485 protocols. It provides two drivers and no receivers, so it handles the transmit side of a differential pair — you pair it with a separate receiver for a full transceiver function. The supply range is 4.75V to 5.25V, which means a clean 5V rail is required; a 3.3V-only system needs a level translator or regulator.
Through-hole package and board fit
Housed in an 8-DIP (0.300-inch, 7.62mm) through-hole package with the supplier device code 8-PDIP, the SN75158P suits prototyping, low-volume builds, or designs where hand-solder assembly is preferred. The 0.100-inch lead pitch is breadboard-friendly and easy to probe during bring-up.
Active production and sourcing posture
The part is ROHS3 compliant.
