1. General description

The HEF4051B-Q100 is a single-pole octal-throw analog switch (SP8T) suitable for use in analog

or digital 8:1 multiplexer/demultiplexer applications. The switch features three digital select inputs

(S1, S2 and S3), eight independent inputs/outputs (Yn), a common input/output (Z) and a digital

enable input (E). When E is HIGH, the switches are turned off. Inputs include clamp diodes. This

enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
