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.
• Dual Versions
• Individual Asynchronous Clear for Each Counter
• Typical Max Count Frequency of 50 MHz
• Input Clamp Diodes Minimize High Speed Termination Effects
