3 Description

The SN74AHC273-Q1 contains eight positive-edgetriggered

D-type flip-flops with a direct active low clear

( CLR) input.

Information at the data (D) inputs meeting the setup

time requirements is transferred to the Q outputs on

the positive-going edge of the clock (CLK) pulse.

Clock triggering occurs at a particular voltage level

and is not related directly to the transition time of the

positive-going pulse. When CLK is at either the high

or low level, the D input has no effect at the output.
