1. General description

The HEF4052B is a dual single-pole quad-throw analog switch (2x SP4T) suitable for use in

analog or digital 4:1 multiplexer/demultiplexer applications. Each switch features four independent

inputs/outputs (nY0, nY1, nY2 and nY3) and a common input/output (nZ). A digital enable input

(E) and two digital select inputs (S1 and S2) are common to both switches. 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 VDD.
