DESCRIPTION

The M74HC590 is an high speed CMOS 8-BIT

BINARY COUNTER REGISTER (3 STATE)

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.

fabricated with silicon gate C MOS technology.

This device contains an 8-bit binary counter that

feeds an 8-bit storage register. The storage

provided for both the binary counter and storage

input CCLR and a count enable input CCKEN. For
