description

The 74AC11590 contains an 8-bit binary counter that feeds an 8-bitstorage register. The storage register has parallel outputs. Separateclocks are provided for both the binary counter and storage register.

The binary counter features a direct clear (CCLR\) input and acount-enable (CCKEN\) input. For cascading, a ripple-carry () output isprovided. Expansion is easily accomplished for two stages byconnecting of the first stage to CCKEN\ of the second stage.Cascading for larger count chains can be accomplished by connecting ofeach stage to CCK of the following stage.

Both the register and the counter have individualpositive-edge-triggered clocks. If both clocks are connectedtogether, the counter state is always one count ahead of theregister. Internal circuitry prevents clocking from the clock enable.

The 74AC11590 is characterized for operation from -40°C to85°C.
