Quad OR gate with Schmitt-trigger inputs — rated for the automotive temperature span
The Texas Instruments SN74HCS32QDRQ1 is a quad 2-input OR gate from the 74HCS logic family, featuring Schmitt-trigger inputs on all four gates. It operates from a 2V to 6V supply and is specified across the full automotive temperature range of -40°C to 125°C. Outputs source and sink 7.8 mA each, enough to drive a downstream gate input or a small LED indicator directly. The 14-SOIC package (3.90 mm body width) is a standard logic footprint that fits existing PCB layouts without a board spin.
