The 7.9 ns max propagation delay at 5V with a 15 pF load sets the timing budget for this gate.
Rated for -40°C to 125°C operating temperature, this gate suits outdoor telecom cabinets, factory-floor sensor interfaces, and engine-bay modules where the ambient swings beyond commercial limits.
Lifecycle status is Active with ROHS3 compliance.
The maximum propagation delay is 7.9 ns at 5V with a 15 pF load. This is the time from input to output transition under those conditions.
The SN74AHC1G00 (peer SN74AHC1G00DBVT) is the 2V to 5.5V supply version with wider voltage range and lower logic thresholds (0.5V to 1.65V low, 1.5V to 3.85V high), but a slightly slower 7.5 ns delay at 5V/50pF. The AHCT variant is optimized for 5V-only systems with fixed TTL-compatible thresholds (0.8V low, 2V high). Choose the AHC version if you need 3.3V compatibility; stick with AHCT for a pure 5V TTL bus.
