NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested.
3. To access RAM, CE = VIL and MBSEL = VIH. To access mailbox, CE = VIH and MBSEL = VIL.
4. 'X' in part numbers indicates power rating (S or L).
5. Refer to Truth Table I.
