It accepts serial data and shifts it through eight stages, presenting the latched output on eight push-pull lines — a straightforward way to expand GPIO on a microcontroller without adding a dedicated SPI port. ## What AEC-Q100 means for the BOM AEC-Q100 qualification is not a single test — it is a suite of stress and reliability screens (high-temperature operating life, temperature cycling, ESD, latch-up) that the part passes before it ships to automotive OEMs. For a shift register feeding an indicator cluster or a body-control serial bus, that qualification means the part's datasheet limits are backed by PPAP-grade data the OEM auditor will ask for. For a production BOM that already qualifies this part, the supply path is straightforward: quoted to order against the line item, with availability confirmed at RFQ. The 1.27 mm pitch is layout-friendly on two-layer boards — no via-in-pad or fine-pitch fan-out needed. Supplied on tape and reel for automated assembly.","metaTitle":"SN74HCS594QDRQ1 TI 74HCS Shift Register, AEC-Q100, 16-SOIC","metaDescription":"Texas Instruments SN74HCS594QDRQ1 automotive-grade 8-bit shift register, 2V-6V supply, -40°C to 125°C.
