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 device terminals except FCT162XXX Output and I/O terminals.
3. Output and I/O terminals for FCT162XXX.

NOTES:
1. A-to-B data flow is shown: B-to-A data flow is similar but uses xCEBA, xCLKBA, and
xOEBA.
2. Level of B before the indicated steady-state input conditions were established.
3. H = HIGH Voltage Level
L = LOW Voltage Level
X = Don't Care
