1. CHARACTERISTICS AND SPECIFICATIONS

(All Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions. Typical

performance characteristics and specifications are derived from measurements taken at nominal supply voltages

and TA = 25°C.)

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.
