1Pin 1 tied to Pin 8, and Pin 4 tied to Pin 6.
2Defined as the average of the input voltages at the low to high and high to low transition points. Refer to Figure 14.
3Defined as half the magnitude between the input voltages at the low to high and high to low transition points. Refer to Figure 14.
4–VS must not be connected above ground.
All min and max specifications are guaranteed. Specifications shown in boldface are tested on all production units at final test.
