AC ELECTRICAL CHARACTERISTICS
NOTES:
1. This is the maximum frequency which can be applied to OSCIN, or, the maximum crystal frequency that can be
2. The values of M, N and the frequency of OSCIN (if used) must be chosen so that this spec is met
3. This is the time from when V
4. When the device is initially powered up, or restored from the power–down mode, OE should be asserted (high).
5. Although OE does not normally affect OUT0 operation, if OE is held low during power–up the start of the t
6. Operation with higher capacitive loads is possible but may impair output voltage swing and maximum operation
