RD74LVC273B
Octal D-type Flip-Flops with Clear
REJ03D0323–0100Z
Rev.1.00
Jun. 16, 2004
Description
The RD74LVC273B 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.
