DESCRIPTION
The M54/74HC393 is a high speed CMOS DUAL
BINARY COUNTER fabricated in silicon gate
C2MOS technology. It has the same high speed
performance of LSTTL combined with true COMS
low power consumption.
This counter circuit contains independent ripple
carry counters and two 4-bit ripple carry binary
counters, which can be cascated 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 od divide by N counter
configurations.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/4 (per Flip Flop)
