SN74LS393

Dual 4−Stage Binary

Counter

The SN74LS393 contains a pair of high-speed 4-stage ripple

counters.

Each half of the LS393 operates as a Modulo-16 binary divider, with

the last three stages triggered in a ripple fashion. In the LS393, 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.
