(Previous ADE-205-396 (Z))
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 flip-flops 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.
