It operates on a 4.5V to 5.5V supply and is specified across the full industrial temperature range of -40°C to 125°C, making it suitable for automotive under-hood and industrial control environments where 5V logic is still the standard. ## Supply rail and logic-level fit This part is a 5V-only device — the supply range is 4.5V to 5.5V, and the input thresholds are 0.8V (low) and 2V (high). That means it will not reliably interpret a 3.3V logic-high as a valid high; if your upstream driver is 3.3V, you need a level translator or a 74AHC variant with lower thresholds. The 8mA symmetric output drive (both high and low) is typical for this logic family and drives one or two standard CMOS loads without issue. ## Propagation delay and timing margin Maximum propagation delay is 7.9ns at 5V with a 15pF load. For a 50 MHz clock path, that delay eats about 40% of a half-cycle — budget it in your timing closure. If you need faster, the 74AHC1G00 (same pinout) offers 7.5ns at 5V, 50pF, but its input thresholds are lower (0.5V to 1.65V low, 1.5V to 3.85V high), which changes the noise margin. ## Package and footprint The DCKT suffix indicates the SC-70-5 (SOT-353) package. It is a 5-lead, 2.0mm × 2.1mm body — small enough for dense layouts but still hand-solderable with a fine tip. The same footprint accepts the 74AHC1G00DBVT (SOT-23-5) if you need a drop-in alternate with a different package outline; verify the land pattern before swapping. ## Lifecycle and sourcing TI lists the SN74AHCT1G00DCKT as Active with ROHS3 compliance.","metaTitle":"SN74AHCT1G00DCKT Single NAND Gate, SC-70-5, -40 to 125°C","metaDescription":"TI SN74AHCT1G00DCKT is a single 2-input NAND gate in SC-70-5, 4.5V-5.5V supply, 7.9ns delay, -40 to 125°C.
