Product details

The Texas Instruments SN74LV374APW is an octal D-type flip-flop with tri-state non-inverted outputs, clocked on the positive edge. It belongs to the 74LV family, designed for low-voltage operation across a 2V to 5.5V supply range.

The 170 MHz maximum clock frequency is the headline speed rating. The 10.1 ns propagation delay at 5V, 50 pF gives a clean timing budget.

Tri-state outputs and output drive

Tri-state, non-inverted outputs let you share a bus with other devices — the output goes high-impedance when the output-enable pin is inactive, so multiple flip-flops can drive the same trace without contention. Each output can sink or source 16 mA, enough to drive a low-current LED or a short unterminated trace. Watch the total package dissipation if you run all eight outputs near the limit simultaneously.

No NRND or EOL flags on record.

Frequently asked questions

Is SN74LV374APW RoHS compliant?

Yes, it is ROHS3 compliant. No exemptions or phase-out issues for EU or medical BOMs.

Can SN74LV374APW operate at 3.3V?

Yes. The supply range is 2V to 5.5V, so 3.3V operation is within spec. Propagation delay will be slightly longer than at 5V, but the part is designed for that rail.

Does SN74LV374APW have tri-state outputs?

Yes, the outputs are tri-state, non-inverted. They can be set to high-impedance for bus sharing.

What is the difference between SN74LV374APW and SN74LV374APWR?

The only difference is the packaging format: SN74LV374APW ships in a tube, while SN74LV374APWR ships on tape and reel. The die, package, and electrical specs are identical.
