Product details

The Texas Instruments SN74LVCU04AD packs six independent inverter gates in a 14-pin SOIC package. It belongs to the 74LVCU family — the unbuffered variant of the 74LVC series, meaning the output follows the input with minimal propagation delay and no added hysteresis. Each of the six channels can sink or source 24 mA, enough to directly drive a small LED or a short PCB trace without an external buffer. Maximum quiescent current is 10 µA. Propagation delay is 3.8 ns at 3.3 V with 50 pF load.

Active production — no LTB worry for new builds

No last-time-buy notice, no end-of-life announcement. ROHS3 compliant, lead-free, and suitable for lead-free reflow profiles. The 14-SOIC package is a common footprint — no exotic land pattern that complicates assembly.

Frequently asked questions

Is SN74LVCU04AD obsolete or active?

Active. Texas Instruments lists the product status as Active with no end-of-life notice. It's still a standard catalog item suitable for new designs.

Is SN74LVCU04AD compatible with 3.3V logic?

Yes. The supply range includes 3.3 V, and the input logic levels are specified for 1.32 V to 2.88 V high and 0.4 V to 0.65 V low, which are well within 3.3 V CMOS and TTL thresholds.

What are the equivalent parts for SN74LVCU04AD?

The closest functional equivalent is the SN74LVU04APWT, also a hex unbuffered inverter in 14-SOIC. It runs on 2.0 V to 5.5 V but drives only 12 mA per channel and has a slower 7 ns propagation delay at 5 V. For 3.3 V designs needing the full 24 mA drive and faster edges, the LVCU04AD is the stronger choice.
