Product details

Single-gate inverter for mixed-voltage logic paths

The SN74AHC1G04DCK3 is a single inverter from TI's 74AHC family, packaged in a 5-lead SC-70-5 (SOT-353). It accepts a supply voltage from 2V to 5.5V, so it runs on either a 3.3V or 5V rail without needing a separate level translator — the input thresholds scale with VCC. Output drive is symmetric at 8 mA source and sink, which keeps the rising and falling edges matched when driving a 50 pF load. The propagation delay is 7.5 ns at 5V and 50 pF, fast enough for most general-purpose logic and signal conditioning paths below 50 MHz.

Supply rails and input thresholds

The low-level input threshold is 0.5V to 1.65V, and the high-level threshold is 1.5V to 3.85V, both referenced to the supply voltage. At VCC=3.3V, a 0.8V low and 2.0V high are typical — compatible with 3.3V CMOS and LVCMOS outputs. Quiescent current is 1 µA maximum, so the part adds negligible static draw to a battery-powered or always-on rail.

Active lifecycle — no obsolescence risk

The SC-70-5 package is widely used and stocked across multiple distributor channels; availability is confirmed per RFQ against your BOM quantity.

Frequently asked questions

Is SN74AHC1G04DCK3 compatible with 3.3V or 5V supply?

Yes. The supply range is 2V to 5.5V, so it works on both 3.3V and 5V rails. The input thresholds scale with VCC, so a 3.3V logic high (typically 2.0V) is above the high-level threshold at VCC=3.3V (1.5V to 3.85V range).

What is the propagation delay of SN74AHC1G04DCK3?

The maximum propagation delay is 7.5 ns at VCC=5V with a 50 pF load. At lower supply voltages the delay increases slightly, but it stays under 15 ns at 3.3V for the same load.

What is the difference between SN74AHC1G04 and SN74LVC1G04?

The SN74LVC1G04 operates down to 1.65V and has 5V-tolerant inputs, while the SN74AHC1G04 has a 2V minimum supply and its inputs are not 5V-tolerant above VCC. The AHC version also has slightly higher propagation delay (7.5 ns vs 4 ns typical at 5V). Both are single inverters in SC-70-5.
