Resumen del producto

The SN74HC590AN is a 8-bit Binary Counter with 3-state output 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.
  • High-current 3-state parallel register outputs can drive up to 15 LSTTL loads
  • Low power consumption, 80µA maximum ICC
  • 14ns Typical TPD
  • ±6mA Output drive at 5V
  • Low input current of 1µA (maximum)
  • 8-bit counter with register
  • Counter has direct clear
