HD74LV273A Datasheet

HD74LV273A Octal D-type Flip-Flops with Clear

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-voltag.
