Product details

The Fairchild MM74HC374J is an 8-bit D-type flip-flop with tri-state, non-inverted outputs, clocked on the positive edge. It runs on a 2V to 6V supply and drives 7.8 mA per output.

The MM74HC374J ships in a DIP package, bulk format. That through-hole footprint is still common on prototype boards, industrial I/O cards, and legacy backplane designs where a surface-mount reflow step is avoided. The 8-bit width and single-element layout (one 8-bit register per package) keeps the board routing clean for byte-wide data buses.

RoHS status is non-compliant, so if your assembly line requires lead-free solder, you will need to verify acceptance or plan for a waiver.

Frequently asked questions

Is MM74HC374J available via RFQ confirmation and what is the lead time?

Stock and lead time are confirmed at quote time. Submit an RFQ and we will provide current availability and estimated lead time for your required volume.

What is the function of the MM74HC374J?

It stores and outputs an 8-bit data word on each clock pulse.

What is the difference between 74HC374 and 74LS374?

The 74HC374 runs on a 2V to 6V supply and draws 8 µA quiescent current, while the 74LS374 is a 5V-only bipolar part with higher power consumption. The HC version is the CMOS low-power choice for new designs; the LS version is legacy and not recommended for new BOMs.
