DESCRIPTION
The M54/74HC590 isa highspeed CMOS8-BIT BI-
NARY COUNTER REGISTER (3-STATE) fabri-
cated in silicon gate C
2
MOS technology. It has the
same high speed performance of LSTTL combined
with true CMOS low power consumption.
These devices each contain an 8-bit binary counter
that feeds an8-bit storage register. Thestoragereg-
ister has parallel outputs. Separate clocks are pro-
vided for both the binary counter and storage
register. The binary counter features a direct clear
input CCLR and a count enable input CCKEN. For
cascading, a ripple carry output RCO is provided.
Expansion is easily accomplished by tying RCO of
the first stage to CCKEN of the second stage, etc.
Both the counter and register clocks are positive-
edge triggered. If the user wishes to connect both
clockstogether, thecounter statewill always be one
count ahead of the register. Internal circuitry pre-
vents clocking fromthe clock enable.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
