MC74HC393A Dual 4-Stage Binary Ripple Counter

Dual 4-Stage Binary Ripple Counter High Performance Silicon Gate CMOS MC74HC393A The MC74HC393A is identical in pinout to the LS393. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL 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 .
