Notes:
1. On CY74FCT162H244T these pins have “bus hold.”
2. H = HIGH Voltage Level. L = LOW Voltage Level. X = Don’t Care. Z = High Importance.
3. Operation beyond the limits set forth may impair the useful lifeofthe device. Unless otherwise noted, these limits are over the operating free-air temperature range.
4. Unused inputs must always be connected to an appropriate logic voltage level, preferably either V
CC
or ground.
