1. General description

The HEF4051B 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.
