Product details

Six unbuffered inverters in a 14-TSSOP — what the 74HCU family brings

The SN74HCU04PW contains six unbuffered inverter gates in a 14-TSSOP package. Supply range is 2V to 6V.

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

2 µA quiescent current — standby budget for always-on logic

Quiescent supply current maxes at 2 µA across the full temperature range. The output drivers sink and source 5.2 mA each — enough to drive a standard CMOS input or a low-current LED indicator, but not a relay coil or a long twisted-pair bus.

Industrial temperature grade — factory floor and outdoor enclosure

No last-time-buy notice, no end-of-life risk for current production.

Frequently asked questions

What is the difference between SN74HCU04PW and SN74HC04?

The key difference is the output buffer stage. SN74HC04 includes a buffered output that sharpens edges and provides higher drive, while the SN74HCU04PW (unbuffered) has a more linear transfer characteristic. The unbuffered version is preferred for analog-style circuits like Pierce crystal oscillators; the buffered 74HC04 is better for pure digital fan-out where you want minimum propagation delay variation.

What are the alternatives to SN74HCU04PW?

The tape-and-reel variant is SN74HCU04PWT, electrically identical. If you need Schmitt-trigger inputs for noisy environments, the 74HCS04 (SN74HCS04PWR) offers hysteresis with similar pinout. For automotive-grade requirements, the SN74HCS14QDRQ1 provides six Schmitt-trigger inverters qualified to AEC-Q100.

Is SN74HCU04PW compatible with 5V logic?

Yes. The supply range of 2V to 6V covers both 3.3V and 5V rails. Input logic thresholds scale with VCC: at 5V supply, the low-level threshold is 0.5V to 1.8V and the high-level threshold is 1.7V to 4.8V, so standard 5V CMOS and TTL outputs drive it directly.
