description

The 74ACT11593 contains eight multiplexed parallel I/Os with3-state output capability and an 8-bit storage register that feeds an8-bit binary counter. Both the register and the counter haveindividual positive-edge triggered clocks.

The function tables show the operation of the counter clock-enable(CCKEN, CCKEN\) and output-enable (OE,) inputs.

The counter input has direct load and clear functions. Alow-goingpulse isobtained when the counter reaches the hex word FF.

Expansion is easily accomplished for two stages by connectingof the first stage to CCKEN\ of thesecond stage. Cascading for larger count chains is accomplished byconnectingof each stageto CCK of the following stage.

The 74ACT11593 is characterized for operation from -40°C to85°C.
