Product details

The Texas Instruments SN74HCS04PWR is a hex inverter from the 74HCS series, packing six independent inverter gates with Schmitt-trigger inputs into a 14-TSSOP package. Each gate accepts a single input and delivers a clean inverted output with hysteresis, which suppresses noise on slow or noisy signal lines — useful in industrial sensor interfaces, pushbutton debounce, and oscillator circuits. The wide supply range from 2V to 6V lets it bridge 3.3V and 5V logic domains without a level shifter, and the -40°C to 125°C operating temperature covers industrial enclosures and under-hood automotive cabin zones.

16 ns propagation delay — what it means for timing closure

At 6V with a 50pF load, the max propagation delay is 16 ns per gate.

Lifecycle status is Active with no NRND or EOL flags. ROHS3 compliant. No last-time-buy window is in effect, and no successor has been announced.

Frequently asked questions

Does SN74HCS04PWR have Schmitt-trigger inputs?

Yes, every input on the SN74HCS04PWR includes a Schmitt trigger, providing hysteresis for noise rejection on slow or noisy signal edges.

What is the equivalent of SN74HCS04PWR?

The SN74HCS14QDRQ1 is a functional equivalent — same 74HCS series, same hex inverter with Schmitt-trigger inputs, same package footprint, same supply and temperature range. The difference is the SN74HCS14QDRQ1 carries AEC-Q100 automotive qualification.
