NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. All devices except Vcc2.
3. Power supply terminal Vcc2.

POWER SUPPLY SEQUENCING
In the 74FCT164245T, the condition of VCC1 ≥ (VCC2 – 0.5V) must be
maintained at all times. For the range of VCC1 = (VCC2 – 0.5V) to VCC1 = (VCC2
+ 0.9V), both the A and B ports will remain in a High-Impedance state.
