NOTES:
1. Voltage values are with respect to network GND.
2. These devices have been designed to be used in applications in which the high-voltage supply, VCC2, is switched to GND before
changing the state of the outputs.

The algebraic convention, in which the least positive (most negative) value is designated as minimum, is used in this data sheet for logic voltage
levels.
