Description

The HD74HC93 is a 4-bit ripple type counter consisting of four master/slave flip-flops that are internally connected to provide separate divide-by-two and divide-by-eight sections. Each section has a separate clock input which initiates state changes of the counter on the high-to-low clock transition.

Features
