DESCRIPTION

The M74HC393 is an high speed CMOS DUAL BINARY COUNTER fabricated with silicon gate

2

MOS technology.

C This counter circuit contains independent ripple carry counters and two 4-bit ripple carry binary counters, which can be cascaded to create a single divide by 256 counter. Each 4-bit counter is incremented on the high to low transition (neg ative edge) of the clock inp ut,

and each has an indep endent clear input. When CLEAR is set to low, all four bits of each count er are set to a low level. This enables count truncation and allows the implementation of divide by N counter configurations. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
