74HC590 8-bit Binary Counter/Register

74HC590 Description

HD74HC590 8-bit Binary Counter/Register (with 3-state outputs) .
This device each contains an 8-bit binary counter that feeds an 8-bit storage register.

74HC590 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 t
