Ripple Counter Integrated Circuits

The 7493 is a four-bit ripple counter with a common reset.
The 7493 can be used as a MOD-2, a MOD-8 or a MOD-16 counter without the reset.
By using the reset inputs, the 7493 can be configured in any Modulo number up to 16.
The 7490 is a four-bit ripple counter that has a divide-by-2 section and a divide-by-5 section.
The 7490 is most commonly used as a decade counter (MOD-10) with reset inputs and set inputs that force the counter to state 9.
The 7492 is a four-bit ripple counter that has a divide-by-2 section and a divided-by-6 section.
The 7492 is most commonly used as a MOD-6 or a MOD-12 counter.
