12-Stage Ripple Carry Binary Counter
The TC74VHC4040 is an advanced high speed CMOS
12-STAGE BINARY COUNTER/DIVIDER fabricated with silicon
gate C
2
MOS 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.
