Single-gate NAND in the 74AUC family
The SN74AUC1G00DCKR is a single 2-input NAND gate from Texas Instruments' 74AUC series, a low-voltage logic family that operates from 0.8 V to 2.7 V. With a maximum quiescent current of 10 µA and propagation delay of 2 ns at 2.5 V into a 30 pF load, the part fits into high-speed, low-power signal paths where a single gate is needed without the overhead of a multi-gate package.
SC-70-5 footprint and board integration
Housed in a 5-pin SC-70-5 (SOT-353) package, the SN74AUC1G00DCKR occupies roughly 2.0 mm × 2.1 mm of board area.
Supply voltage and logic-level thresholds
The 0.8 V to 2.7 V supply range covers the common 1.2 V and 1.8 V logic rails used in modern SoCs and FPGAs. The low-level input threshold accepts signals from 0 V to 0.7 V, while the high-level threshold is fixed at 1.7 V — meaning a 1.8 V CMOS output drives it cleanly, but a 1.2 V output may not reach the high threshold without a level shifter.
Output drive and switching speed
Symmetrical 9 mA source and sink drive at the output means the gate can switch capacitive loads like a single CMOS input or a short PCB trace without noticeable edge degradation. The 2 ns propagation delay at 2.5 V into 30 pF keeps the signal path clean for clock rates up to roughly 100 MHz in a point-to-point link.
