UNISONIC TECHNOLOGIES CO., LTD U74HC590 8-BIT BINARY COUNTERS WITH 3-STATE OUTPUT REGISTERS CMOS IC  DESCRIPTION The UTC 74HC590 contains an 8-bit binary counter that feeds an 8-bit storage register and 3-state outputs.. The storage register has parallel (QA~QH) outputs. 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.  FEATURES * Wide supply voltage range from 2.0V to 6.0V * Low static power consumption; ICC=8μA (Max.
