High Speed CMOS Logic Octal D-Type Flip-Flops with Reset

The CD54HC273, CD74HC273, CD54HCT273, and

CD74HCT273 high speed octal D-Type flip-flops with

a direct clear input are manufactured with silicongate

CMOS technology. The devices possess the

low power consumption of standard CMOS integrated

circuits.

Information at the D input transfers to the Q outputs

on the positive-going edge of the clock pulse. All eight

flip-flops are controlled by a common clock (CLK) and

a common reset (/CLR). Resetting is accomplished by

a low voltage level independent of the clock. All eight

Q outputs reset to a logic 0.
