Overview
HD74LV273A Octal D-type Flip-Flops with Clear ADE-205-273 (Z) 1st Edition April 1999 Description The HD74LV273A has eight edge 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.
