Refer to Figure 6. 2Defined as half the magnitude between the input voltages at the low to high and high to low transition points. Refer to Figure 6. 3+VS must be no lower than (VLOGIC –0.5 V) in any supply operating conditions, except during power up. All min and max specifications are guaranteed. Specifications shown in
