Note 3: OUTPUT and CLAMP pins not connected.
Note 4: See Output Clamp section for details.
Note 5: All pins are designed to withstand electrostatic discharge (ESD) levels in excess of 2000V (MIL STD 8838 Method 3015.1
test circuit).
Note 6: Sample tested. Limits are not used to calculate outgoing quality level.
