74VHC273
Octal D-Type Flip-Flop
General Description
The VHC273 is an advanced high speed CMOS Octal D-
type flip-flop fabricated with silicon gate CMOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low
power dissipation.
The register has a common buffered Clock (CP) which is
fully edge-triggered. The state of each D input, one setup
time before the LOW-to-HIGH clock transition, is trans-
ferred to the corresponding flip-flop’s Q output. The Master
Reset (MR) input will clear all flip-flops simultaneously. All
outputs will be forced LOW independently of Clock or Data
inputs by a LOW voltage level on the MR input.
An input protection circuit insures that 0V to 7V can be
applied to the inputs pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery backup. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
Features
