DESCRIPTION
The M74HC393 is an high speed CMOS DUAL
BINARY COUNTER fabricated with silicon gate
C2MOS technology.
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 (negative edge) of the clock input,
and each has an independent clear input. When
CLEAR is set to low, all four bits of each counter
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.
