Product details

Quad buffer with 3-state — 5 V logic workhorse

The 3-state control lets you float the outputs for shared data lines or bidirectional buses without external tristate buffers.

Industrial temperature — factory-floor safe

No extended or automotive temperature grade here — if you need -40°C to 125°C, look at the 74LVC or 74AHCT families with AEC-Q100 qualification.

14-SOIC package — common footprint, easy rework

Housed in a 14-SOIC (3.90 mm width) package, the SN74HCT125DR uses a standard, widely stocked footprint. MSL 1 (no moisture sensitivity) means no bake before reflow, even after the bag has been open. Store the reels dry, but you have a generous floor-life window.

Active lifecycle — no LTB worry

No end-of-life notice on the horizon.

Frequently asked questions

What is the difference between SN74HCT125DR and SN74HCT125D?

The SN74HCT125D is the tube-packaged version of the same die; the SN74HCT125DR is the Tape & Reel variant. Electrical specs and footprint are identical.

What is the difference between 74HCT125 and 74HC125?

The 74HC125 runs on 2 V to 6 V with CMOS-level input thresholds; the 74HCT125 is optimized for 5 V operation and has TTL-compatible input thresholds, making it a direct drop-in for 5 V TTL logic systems.
