Description

The HD74LV273A has eight edges trigger D-type flip-flops with clear in a 20-pin package. Data on the D input having

the specified setup and hold times is transferred to the Q output on the low to high transition of the clock input. The

clear input when low sets all outputs to a low state. Low-voltage and high-speed operation is suitable for battery-

powered products (e.g., notebook computers), and the low-power consumption extends the battery life.
