NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VDD + and VDD −.

2. Connecting any terminal to voltages greater than VDD + or less than VDD − may cause destructive latch-up. No sources operating from

external supplies should be applied prior to device power up.

3. The output may be shorted to either supply.
