Refer to Figure 6. 3Defined as half the magnitude between the input voltages at the low to high and high to low transition points. Refer to Figure 6. 4–V S 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. Specifications subject to change without notice. AD790 REV. D –3– (Operation @ 25 C and +VS = VLOGIC = 5 V, –VS = 0 V unless otherwise noted.) 1 |
