12-Stage Ripple Carry Binary Counter

The TC74VHC4040 is an advanced high speed CMOS

12-STAGE BINARY COUNTER/DIVIDER fabricated with silicon

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

Setting CLR to high resets the counter to low.

A negative transition on the CK input brings one increment

into the counter.

This counter provides all divided output stages, and at Q12, a

1/4096 divided frequency will be output.

An input protection circuit ensures that 0 to 5.5 V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.

Features

• Power down protection is provided on all inputs.

• Pin and function compatible with 74HC4040
