Octal D-Type Flip-Flop with Reset

Features

Description

• Common Clock and Asynchronous Master Reset

• Positive Edge Triggering

• Buffered Inputs

The Harris CD74HC273 and CD74HCT273 high speed octal

D-Type flip-flops with a direct clear input are manufactured

with silicon-gate CMOS technology. They possess the low

power consumption of standard CMOS integrated circuits.

Information at the D inputis transferred to the Q outputs on

the positive-going edge of the clock pulse. All eight ﬂip-ﬂops

are controlled by a common clock (CP) and a common reset

(MR). Resetting is accomplished by a low voltage level

independent of the clock. All eight Q outputs are reset to a

logic 0.
