1 Logic Compatibility

The fundamental concept of the threshold levels (VIH, VIL, VOH, VOL) are expanded on in this TI Precision Labs training video - Output/input logic levels (VOH, VOL, VIH, VIL). The following information builds upon the basic understanding of these thresholds based on the information provided in this video.

To check the compatibility between any device’s logic inputs and the pre-existing driver, a simple comparison of the VOH and VOL levels of the driver versus the VIH and VIL thresholds of the multiplexer in question can be done. The following is a more in-depth explanation on how to check the VIH and VIL compatibility of your TMUX405x when used in a system that has a pre-existing CD405x or CD74HCx405x designed in.
