The CD74HCT00E: Input logic-low threshold is 0.8 V max, and logic-high is 2 V min — the 5 V TTL-compatible levels mean this gate interfaces directly with 5 V microcontrollers and legacy bus logic without external level shifting. Quiescent current sits at 2 µA max, keeping the power budget tight in always-on or battery-backed sections of the board.
