Quad NAND gate with Schmitt-trigger inputs — what it does and where it fits
The Texas Instruments SN74HCS00PWR is a quad 2-input NAND gate from the 74HCS series, each channel equipped with a Schmitt-trigger input. That Schmitt-trigger front end is the headline feature: it takes a noisy, slow, or bouncing signal — think a mechanical switch, a long unshielded cable, or a sensor output with slow edges — and produces a clean logic output without external hysteresis components. The part operates across a 2V to 6V supply range, so it sits comfortably on either a 3.3V or 5V rail without a level translator. With an operating temperature range of -40°C to 125°C, it is rated for industrial environments, outdoor telecom cabinets, and under-hood automotive zones (though not AEC-Q100 qualified per the evidence). The 14-TSSOP package (4.40 mm width) is a common footprint for board-level glue logic; the 7.8 mA output drive is enough to fan out to a few CMOS loads or drive a small LED through a resistor.
12 ns propagation delay — what it means for timing
The maximum propagation delay is 12 ns at 6V supply with a 50 pF load.
Active lifecycle — no obsolescence watch needed
The SN74HCS00PWR is listed as Active in production status, with ROHS3 compliance. That means you can design it into a new BOM today without worrying about a last-time-buy notice in the next quarter. Texas Instruments continues to manufacture the 74HCS series as a mainstream logic family. No successor or second-source alternate is listed in the evidence, but the part is widely available through independent distribution. If you need a second-source NAND gate, the SN74LV00APWR is a 74LV-series quad NAND with a narrower temperature range (85°C) and no Schmitt trigger, so verify the application first.
Sourcing and availability
This part is sourced to order through independent distribution. We confirm current pricing and availability at quote time against an RFQ. No stock or lead-time numbers are published here because the market moves daily, but the part is active and in regular production — not a hard-to-find or end-of-life item. Submit an RFQ for your target quantity and we will return a firm price and delivery window.
