Overview
The HEF4052BT, produced by Nexperia USA Inc., is a dual single-pole quad-throw analog switch (2x SP4T) designed for use in analog or digital 4:1 multiplexer/demultiplexer applications. This component is part of the HEF4000 family of CMOS logic ICs, known for their low power consumption and high operating speeds. Each switch features four independent inputs/outputs (nY0, nY1, nY2, and nY3) and a common input/output (nZ), along with a digital enable input (E) and two digital select inputs (S1 and S2) that are common to both switches. When the enable input (E) is HIGH, the switches are turned off. The inclusion of clamp diodes allows for the use of current limiting resistors to interface inputs to voltages in excess of VDD.
