description/ordering information
The ’HC590A devices contain 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 direct clear (CCLR) and count-enable (CCKEN) inputs. A ripple-carry output (RCO) 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.
CCLK and the register clock (RCLK) inputs are positive-edge triggered. If both clocks are connected together,
the counter state always is one count ahead of the register. Internal circuitry prevents clocking from the clock
enable.
