FEATURES
* Fully synchronous operation * Multiplexed 3-State I/O ports for bus oriented applications * Built in cascading carry capability * U/D pin to control direction of counting * Separate pins for Master reset and Synchronous operation * Center power pins to reduce effects of package inductance * Count frequency 115MHz Typ * Supply current 100mA Typ * See 74F269 for 24-pin separate I/O port version * See 74F779 for 16-pin version
DESCRIPTION
The 74F579 is a fully synchronous 8-stage Up/Down Counter with multiplexed 3-State I/O ports for bus-oriented applications. It features a preset capability for programmable operation, carry look-ahead for easy cascading and a U/D input to control the direction of counting. All state changes, except for the case of asynchronous reset, are initiated by the rising edge of the clock. TC output is not recommended for use as a clock or asynchronous reset due to the possibility of decoding spikes.

ICCZ 105 150 mA NOTES: 1. For conditions shown as MIN or MAX, use the appropriate value specified under Recommended Operating Conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25C. 3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter test, IOS tests should be performed last.
