HITACHI HD74HC590

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 the register, Internal circuitry prevents
clocking from the clock enable.
