DC ELECTRICAL CHARACTERISTICS (GND = 0 V; all voltages with respect to 0 V.)

Notes: 2. Power Down Mode is defined as RST = LO with all clocks and data lines held static.

3. Normal operation is defined as RST = HI.

4. Assumes that no inputs are left floating. It is recommended that all digital inputs be driven high or low

at all times.
