description

The 'ACT11592 consists of a parallel input and an 8-bit storage register feeding an 8-bit binary counter. Both the register and the counter have individual positive-edge triggered clocks.

The counter () input has direct load and clear functions. A low-going pulse will be obtained when the counter reaches the hex word FF.

Expansion is easily accomplished for two stages by connecting of the first stage to of the second stage. Cascading for larger count chains can be accomplished by connecting of each stage to CCK of the following stage.

The 54ACT11592 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74ACT11592 is characterized for operation from -40°C to 85°C.
