Product details

155 MHz octal D-type — what it is and where it fits

The Texas Instruments SN74AC374PW is an octal D-type flip-flop from the 74AC family, clocked at 155 MHz on a positive edge. Each of the eight flip-flops presents a non-inverted, tri-state output.

9.5 ns propagation delay — timing margin for the bus

At 5 V with a 50 pF load, the max propagation delay is 9.5 ns. That number sets the clock-to-Q window you need to budget for setup and hold on the receiving end.

Active, no LTB risk — sourcing posture

The SN74AC374PW carries an active lifecycle status, so there is no last-time-buy clock ticking. This is a current-production part from TI's 74AC catalog, ROHS3 compliant. For a BOM line that needs a registered octal buffer with tri-state outputs, this part is a straightforward fit — no end-of-life planning needed, no substitute qualification required.

Frequently asked questions

What is the closest functional alternative to SN74AC374PW?

The 74F374SCX-NS is a similar octal D-type with tri-state outputs and positive-edge trigger, but it runs on a 4.5 V supply only, has a 140 MHz clock, and is rated 0°C to 70°C — commercial temperature only. The SN74AC374PW covers the full industrial range and accepts 2V to 6V, so it is the more flexible choice for mixed-voltage or extended-temperature designs.
