NOTES:
(a) The electrical specifications in this document for both the 8.39 and 16.78 MHz @ 3.3 V ±0.3 V are preliminary,
and apply only to the appropriate MC68340V low voltage part.
(b) The 16.78-MHz specifications apply to the MC68340 @ 5.0 V ±5% operation.
(c) The 25.16 MHz @ 5.0 V ±5% electrical specifications are preliminary.
(d) For extended temperature parts T _A = –40 to +85°C. These specifications are preliminary.
