SL74HC393 - Dual 4-Stage Binary Ripple Counter
SL74HC393 Dual 4-Stage Binary Ripple Counter High-Performance Silicon-Gate CMOS The SL74HC393 is identical in pinout to the LS/ALS393.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
This device consists of two independent 4-bit binary ripple counters with parallel outputs from each counter stage.
A÷256 counter can be obtained by cascading the two binary counters.
Internal flip-flops are triggered by high-to-low tra
