Note:
Permanent device damage can occur if the above absolute maximum ratings are exceeded. Restrict functional
operation to the conditions as specified in the operational sections of this data sheet. Exposure to absolute maximum
rating conditions for extended periods might 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
V
IH
=
V
D
– 0.4 V, V
IL
=
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 M are typically connected to V
D
or GND and should not be changed during normal operation.
