The Schmitt trigger on each of the four inputs cleans up noisy or slow-rising digital signals — it adds hysteresis so a glitchy encoder pulse or a long-trace clock line won't cause multiple edges at the output. The 3-state output lets you tie multiple buffers to the same data bus; when the output enable is low, the pin goes high-impedance and another device drives the line. ## Temperature range and drive capability for industrial use Rated for -40°C to 125°C ambient, this buffer handles the thermal swing of an outdoor telecom enclosure or an engine-bay controller without derating. Each output sources or sinks 7.8 mA — enough to drive a standard CMOS logic input or a low-power LED indicator, but not a relay coil. The wide supply range (2V to 6V) means it works from a 3.3V or 5V rail without a separate level translator, as long as the input thresholds align. ## Package and hand-solderability for prototyping and rework Housed in a 14-TSSOP package (4.40 mm wide, 0.65 mm pin pitch), the SN74HCS126PWR is hand-solderable with a fine-tip iron and some flux — no hot-air station required if you're careful. The 0.65 mm pitch is forgiving enough for a breakout board or a prototype PCB. Tape & Reel or Cut Tape options are available, so you can grab a handful for a weekend build without committing to a full reel.","metaTitle":"SN74HCS126PWR Texas Instruments Buffer, 3-State, 14-TSSOP","metaDescription":"Active TI SN74HCS126PWR quad non-inverting buffer with Schmitt trigger inputs, 2V-6V supply, 7.8mA drive, -40°C to 125°C. 14-TSSOP.

The SN74HCS126PWR is a quad buffer in a 14-TSSOP.
