SN74LS393, SN74LS393N Datasheet (ON Semiconductor)

SN74LS393, SN74LS393N, Dual 4-Stage Binary Counter

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.
