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.
