backup. This circuit prevents device destruction due to mis-

matched supply and input voltages.

General Description

The VHC4040 is an advanced high-speed CMOS device

fabricated with silicon gate CMOS technology. It achieves

the high-speed operation similar to equivalent Bipolar

Schottky TTL while maintaining the CMOS low power dissi-

pation. The VHC4040 is a 12-stage counter which incre-

ments on the negative edge of the input clock and all

outputs are reset to a low level by applying a logical high

on the reset input. An input protection circuit insures that

0V to 7V can be applied to the inputs without regard to the

supply voltage. This device can be used to interface 5V to

3V systems and two supply systems such as battery

Features

■ High speed; f_MAX= 210 MHz 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)

■ Power down protection is provided on all inputs

■ Wide operating voltage range: V_CC(opr) = 2V − 5.5V

■ Low noise: V_OLP= 0.8V (max)

■ Pin and function compatible with 74HC4040
