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.

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.

Features

■ High Speed: f_MAX= 165 MHz (typ) at V_CC= 5V

■ Low power dissipation: I_CC= 4 µA (max) at T_A= 25°C

■ High noise immunity: V_NIH= V_NIL= 28% V_CC(min)

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.

■ Power down protection is provided on all inputs

■ Low noise: V_OLP= 0.9V (max)

■ Pin and function compatible with 74HC273

An input protection circuit insures that 0V to 7V can be

applied to the inputs pins without regard to the supply volt-
