Description
The M74HC590 is an high speed CMOS 8-BIT.
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 cir.
