Overview
HD74HC590
8-bit Binary Counter/Register (with 3-state outputs)
Description
This device each 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 C CKEN.
For cascading a ripple carry output R CO is provided.
Expansion is easily accomplished by tying R CO 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 th...
