Product details

Single-gate buffer for mixed-voltage and industrial logic

The Texas Instruments 74AHC1G126DCKRE4 is a single-bit, non-inverting buffer with a 3-state output, part of the 74AHC logic family.

The 2V to 5.5V supply span lets this buffer bridge 3.3V and 5V domains without an external level shifter, as long as the input thresholds are compatible. The single-gate SC-70-5 package saves board area when you need just one buffer channel on a dense PCB.

Listed as Active by TI. The base product number 74AHC1G126 covers multiple reel and package variants — the DCKRE4 suffix specifies the SC-70-5 reel.

Frequently asked questions

Is 74AHC1G126DCKRE4 obsolete?

No, the product status is Active. No phase-out or last-time-buy has been announced.

What is the difference between 74AHC1G126 and 74AHC1G125?

Both are single non-inverting buffers with 3-state output. The 74AHC1G126 uses an active-high output enable; the 74AHC1G125 uses an active-low enable. Pinouts differ accordingly.
