14-Stage Ripple Carry Binary Counter
The TC74VHC4020 is an advanced high speed CMOS 14-STAGE
BINARY COUNTER/DIVIDER fabricated with silicon gate C2MOS
technology.
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.
