Introduction

Common multiplexers are usually designed to pass voltage signals equal or less than their power supply. In most system applications this can suffice, but in unique cases where there is a need to pass a signal exceeding the power supply, Beyond the Supply multiplexers can be used. These multiplexers have the capability to allow to pass a signal that exceeds their supply or falls below ground, despite not having a negative rail. The Beyond the Supply feature has three different types of operations.
