Recommended Operating Conditions
For proper operation, the device should be used within the recommended conditions. All voltage parameters
are absolute voltages referenced to COM . The offset rating are tested with supplies of (VCC-COM) = (VB-
VS)=15V.

V S and V B voltages will be tolerant to short negative transient spikes. These will be defined and
specified in the future.
Logic operation for Vs of -5 to 600V. Logic state held for Vs of -5V to –V BS . (Please refer to Design
Tip DT97-3 for more details).
