DYNAMIC SWITCHING THRESHOLD

Dynamic switching threshold is the change in VIH and VIL when the device is operated in various switching and output loading conditions. The

cause of this variation is due to extra load placed on internal circuit structures. VIHD and VILD are measures of the dynamic switching threshold.

VIHD is the input high switching level when the device is heavily loaded. VILD is the input low switching level when the device is heavily loaded.
