HD74HC393 General Description

The HD74HC393 contain two 4-bit ripple carry binary counters, which can be cascaded to create a single divide-by-256 counter. The HD74HC393 is incremented on the high to low transition (negative edge) of the clock input, and each has an independent clear input. when clear is set high all four bits o.
