1. General description

The HEF4053B is a triple single-pole double-throw analog switch (3x SPDT) suitable for use in

analog or digital 2:1 multiplexer/demultiplexer applications. Each switch features a digital select

input (Sn), two independent inputs/outputs (Y0 and Y1) and a common input/output (Z). A digital

enable input (E) is common to all 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.
