Notes:
1. On the CY74FCT162H952T these pins have bus hold.
2. A-to-B data flow is shown: B-to-A data flow is similar but uses, CEBA, CLKBA, and OEBA.
3. H = HIGH Voltage Level.
L = LOW Voltage Level.
X = Don’t Care.
= LOW-to-HIGH Transition.
Z = HIGH Impedance.
4. Level of B before the indicated steady-state input conditions were established.
5. 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.
6. Unused inputs must always be connected to an appropriate logic voltage level, preferably either V_CC or ground.
