DESCRIPTION
The M54HC590 is an high speed CMOS 8-BIT
BINARY
COUNTER
REGISTER
(3
STATE)
fabricated with silicon gate C2MOS technology.
This device contains an 8-bit binary counter that
feeds an 8-bit storage register. The storage
register has parallel outputs. Separate clocks are
provided 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
clocks together, the counter state will always be
one count ahead of the register. Internal circuitry
prevents clocking from the clock enable. All inputs
are equipped with protection circuits against static
discharge and transient excess voltage.
