The Schmitt trigger on every input cleans up slow edges and noise. ## 2 V to 6 V supply — mixed-voltage glue logic The 7.8 mA output drive at 2 V to 6 V supply range provides sufficient drive for typical logic loads. The 125°C ceiling covers the hot side of a sealed enclosure near a power supply or motor controller. The 14-WQFN package with exposed pad helps keep the junction temperature within limits when all four buffers are switching simultaneously at high frequency. ## 14-WQFN footprint — what the layout engineer needs That is a compact footprint — roughly the size of two 0603 passives side by side. The pad also provides a low-inductance ground return for the 3-state outputs, which helps keep signal integrity clean when the outputs switch into a capacitive load. No special orientation marking beyond the standard pin-1 dot; the part is symmetrical enough that a quick visual check before reflow catches a 180° rotation.","metaTitle":"SN74HCS125BQAR Buffer, Non-Inverting, 3-State, 2V-6V","metaDescription":"Texas Instruments SN74HCS125BQAR quad buffer with Schmitt trigger inputs, 3-state outputs, 2V to 6V supply, -40°C to 125°C, 14-WQFN.
