It operates from a 2V to 6V supply, making it a drop-in for both legacy 5V logic and newer 3.3V systems. The 3-state outputs let you isolate multiple bus segments or drive shared lines without contention. With four independent buffers in a single 14-SOIC package, it consolidates board space compared to discrete transistor or gate-level solutions. ## 2V to 6V supply — fits mixed-voltage boards The wide 2V to 6V supply range means this buffer works on 3.3V, 5V, or even unregulated battery rails without a separate level translator. If you need more fanout, plan a buffer stage or use a higher-drive family like 74HCT or 74ACT. The 74HC family's CMOS construction keeps quiescent current low across temperature, so you don't lose much margin at the hot end. ## Active lifecycle — no EOL scramble The 74HC series is a mature logic family with multiple sources. If TI phases out this package, pin-compatible alternatives exist from other manufacturers. ## 14-SOIC footprint — standard and easy to route The 14-SOIC (3.90mm body width) is a common surface-mount package. No exposed pad means no thermal-via stitching — just standard soldering.","metaTitle":"CD74HC126MT 74HC Buffer, Non-Inverting, 3-State, 2V-6V","metaDescription":"CD74HC126MT quad 1-bit buffer with 3-state outputs, 2V to 6V supply, -55°C to 125°C range.
