Product details

Single-gate buffer with wide supply tolerance

The 74LVC1G125DCKTG4 is a single-bit non-inverting buffer with 3-state output from TI's 74LVC family, operating from 1.65 V to 5.5 V. Output sink and source capability is 32 mA each, enough to drive LED indicators, relay coils through a pre-driver, or a short PCB trace to another logic input without a separate line driver.

Temperature grade and package

The SC-70-5 (SOT-353) package occupies 2.0 mm × 2.1 mm, a footprint that fits dense mixed-signal boards where board space is at a premium. Surface-mount assembly with MSL 1 (moisture sensitivity level) per the 74LVC family standard — no bake-out required before reflow, simplifying the production line setup.

Sourcing and lifecycle posture

The base product number 74LVC1G125 covers multiple package and tape options — the DCKTG4 suffix specifies the SC-70-5 package in tape-and-reel. No direct pin-compatible second source is recorded; the 74LVC1G125DCKR (same die, different reel quantity) is the closest order-code variant within the same family.

Frequently asked questions

Is 74LVC1G125DCKTG4 RoHS compliant?

Yes, the DCKTG4 suffix indicates a green (RoHS-compliant) package with no lead, mercury, cadmium, or other restricted substances per TI's material declaration.

What is the difference between 74LVC1G125DCKTG4 and 74LVC1G125DCKR?

Both share the same die and SC-70-5 package. The DCKTG4 is supplied in tape-and-reel (TR) format, while the DCKR variant uses a different reel quantity or packaging code. Electrically identical — the choice is a logistics decision based on the pick-and-place reel size.
