DESCRIPTION
The M54/74HC4518/4520 are high speed CMOS
DUAL 4 BIT BINARY COUNTERS fabricated in sili-
con gate C2MOS technology. They have the same
high speed performance of LSTTL combined with
true CMOS low power consumption.
They consists of two identical internally syn-
chronous 4-stage counters. The counter stages are
D-type flip-flops having interchangeable Clock and
ENABLE inputs for incrementing on either the posi-
tive-going or negative-going transition.
For single-unit operation the ENABLE input is main-
tained ”high” and the counter advances on each
positive-going transition of the CLOCK. The
counters are cleared by high levels on their clear
lines. The counter can be cascaded in the ripple
mode by connecting Q4 to the enable input of the
subsequent counter while the clock input of the latter
is held permanently low.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
