Product Summary
The SN74HC590ADWR is an 8-bit binary counter with 3-state output registers. It has parallel outputs. Separate clocks are provided for both the binary counter and storage register. The binary counter features direct clear (CCLR) and count-enable (CCKEN) inputs. A ripple-carry output (RCO) of the SN74HC590ADWR is provided for cascading. Expansion is accomplished easily for two stages by connecting RCO of the first stage to CCKEN of the second stage. Cascading for larger count chains can be accomplished by connecting RCO of each stage to the counter clock (CCLK) input of the following stage.
