DIGITAL CHARACTERISTICS

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

POWER AND THERMAL CHARACTERISTICS

(GND = 0 V; all voltages with respect to 0 V. HP_x outputs unloaded.)

Notes:

Power Down Mode is defined as RST = LOW with all clocks and data lines held static.

Normal operation is defined as RST = HI.
