Overview
HD74AC393
Dual Modulo-16-Counter
Description
The HD74AC393 contains a pair of high speed 4-stage ripple counters.
Each half of the HD74AC393 operates as a modulo-16 binary divider, with the last three stages triggered in a ripple fashion.
The flipflops are triggered by a High-to-Low transition of their CP inputs.
Each half of each circuit type has a Master Reset input which responds to a High signal by forcing all four outputs to the Low state.
