Product details

Maximum propagation delay is 14 ns at 6V with a 50 pF load.

Logic levels and input thresholds

Low-level input threshold is 0.5V to 1.8V; high-level is 1.7V to 4.8V, depending on supply. At 5V, a typical low is below 1.5V and a high above 3.5V — compatible with 3.3V CMOS logic driving the input. No Schmitt-trigger hysteresis, so the input must transition cleanly; a slow edge on a long trace may cause oscillation. For noisy environments, the SN74HCS04PWR adds Schmitt-trigger inputs but runs at a slightly slower 16 ns delay.

The 14-TSSOP body is 4.40 mm wide.

Frequently asked questions

What is the equivalent part for SN74HCU04PWT?

The SN74HCS04PWR is a pin-compatible alternative in the same 14-TSSOP package with Schmitt-trigger inputs and a 16 ns propagation delay at 6V. For a faster 7 ns option at 5V, consider the SN74LVU04APWT, though it uses a different supply range.

What are the logic levels for SN74HCU04PWT?

Low-level input threshold is 0.5V to 1.8V; high-level input threshold is 1.7V to 4.8V, depending on the supply voltage. Outputs swing rail-to-rail.
