Note: Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional operation
should be restricted to the conditions as specified in the operational sections of this data sheet. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

Notes:
1. All timing (except Rise and Fall time) is referenced to the 50% level of the waveform. Input test levels are
VIH = VD – 0.4 V, VIL = 0.4 V. Rise and Fall times are referenced to the 20% and 80% levels of the waveform.
2. The minimum RESET pulse width is the greater of 250 ns or 10 MCLK cycle times.
3. M0 and M1 are typically connected to VD or GND and should not be changed during normal operation.
