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.","metaTitle":"74AHC1G126DCKRE4 Buffer, Non-Inverting, 3-State, 2V-5.5V","metaDescription":"Texas Instruments 74AHC1G126DCKRE4 single buffer with 3-state output, 2V to 5.5V supply, -40°C to 125°C.
