DESCRIPTION
The M54/74HC4518/4520 are high speed CMOS
DUAL 4 BIT BINARY COUNTERS fabricated in sili-
con gate C
2
MOS technology. Theyhave 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 theposi-
tive-going or negative-going transition.
Forsingle-unit operation theENABLE input ismain-
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
subsequentcounterwhiletheclockinput ofthelatter
is heldpermanently low.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
