NOTE:
1. This parameter is measured at characterization but not tested.
FUNCTION TABLE
NOTES:
1. A-to-B data flow is shown. B-to-A data flow is similar but uses OEBA, LEBA,
2. Output level before the indicated steady-state input conditions were established.
3. Output level before the indicated steady-state input conditions were established,
4. H = HIGH Voltage Level
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
2. All device terminals except FCT162XXX Output and I/O terminals.
3. Output and I/O terminals for FCT162XXX.
