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 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.
