Product Overview
The SN74LVC1G79DCKT is a single positive-edge-triggered D-type flip-flop from Texas Instruments, designed for 1.65-V to 5.5-V VCC operation. It features a single D input with a clock (CLK) input and a non-inverting output (Q). The device is available in a small SC-70-5 package, making it ideal for space-constrained applications. The SN74LVC1G79DCKT offers a typical propagation delay of 5 ns and low power consumption, with a maximum ICC of 10 μA. It supports partial-power-down mode using Ioff circuitry, which prevents damaging current backflow when the device is powered down.
