NOTES:

1. +2.7

≤ V

DD ≤ +3.3 V, VSS = 0 V, TL ≤ TA ≤ TH, unless otherwise noted

2. The minimum period, tILIL, should not be less than the number of cycle times it takes to execute the interrupt service

routine plus 21 tCYC.

3. The 500 kHz nominal mask option is available through special order only. Contact your local Motorola sales

representative for detailed ordering information.
