Single NAND gate that bridges voltage domains
Its 1.6V to 5.5V supply range is the headline feature: this part acts as a voltage-level translator in addition to its logic function. A 1.8V input on the low side can drive a 3.3V or 5V output, and vice versa, without needing a separate level-shifter IC.
7 ns propagation delay — timing budget for mixed-voltage buses
At 5V with a 30pF load, the max propagation delay is 7 ns. The delay increases at lower supply voltages — the input logic thresholds shift with VCC, so a 1.8V system will see a longer propagation path. For timing closure, budget the worst-case delay at the actual operating voltage, not the 5V figure.
8 mA output drive — enough for a single load, not a bus
The output can sink or source 8 mA at both logic levels. That drives one standard CMOS input, a small LED through a series resistor, or the enable pin of a regulator. It will not drive a 50-ohm backplane or a bank of optocouplers without buffering. The 10 µA quiescent current is negligible for battery-powered designs.
It is ROHS3 compliant and remains a valid new-design choice. For production BOMs, the wide supply range and extended temperature grade make it a stable single-sourced line item; if dual-sourcing is required, the closest functional peer is the SN74AHC1G00DBVT, which has a narrower 2.0V to 5.5V supply range and a slightly different input threshold window.
