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 life of the 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 VCC or ground.
