GND 8 7 Ground
NC 7, 12, 17 − No internal connection
OC 9 8 O Logic-level overcurrent reporting output that goes low when an overcurrent conditions exists
SHDN 20 16 I Logic input that shuts down the device and sets all power outputs to high-impedance state
VCCD0 1 1 I Logic input that controls voltage of AVCC (see control-logic table)
VCCD1 2 2 I Logic input that controls voltage of AVCC (see control-logic table)
VPPD0 19 15 I Logic input that controls voltage of AVPP (see control-logic table)
VPPD1 18 14 I Logic input that controls voltage of AVPP (see control-logic table)

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
