74HC393 Datasheet (ON Semiconductor) - Dual 4-Stage Binary Ripple Counter

74HC393, Dual 4-Stage Binary Ripple Counter

MC74HC393 Dual 4 Stage Binary Ripple Counter High Performance Silicon Gate CMOS The MC54/74HC393 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.
