It provides 2 drivers and 0 receivers in an 8-SOIC package, making it a pure transmit-side component for differential pair signaling. The supply voltage range of 4.75V to 5.25V ties it to a 5V nominal rail — common in legacy telecom and industrial control backplanes. ## Package and footprint reality Housed in an 8-SOIC (0.154\", 3.90mm width) surface-mount package, the SN75158D uses the standard SOIC-8 footprint shared by hundreds of logic and interface parts. The 1.27 mm pin pitch is board-friendly — two-layer PCBs fan out easily, and rework with a hot-air station is straightforward. The supplier device package is listed as 8-SOIC, confirming the industry-standard body width. For reel/tape quantities, confirm the alternate ordering code with your distributor. ## Active production — no end-of-life pressure No stock-holding claim is made here — we source per RFQ.","metaTitle":"SN75158D RS422/RS485 Driver 8-SOIC – Texas Instruments","metaDescription":"Active RS422/RS485 dual line driver in 8-SOIC. 4.75V–5.25V supply, commercial temp.
