High-Speed CMOS Logic

Octal D-Type Flip-Flop with Reset

February 1998 - Revised May 2003

Features

Description

• Common Clock and Asynchronous Master Reset

• Positive Edge Triggering

• Buffered Inputs

The ’HC273 and ’HCT273 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.
