Overview
The HEF4052BT,652, 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 HEF4052B series and is housed in a 16-pin SOIC (SOT109-1) package. Although the HEF4052BT,652 is currently withdrawn and end-of-life, it remains relevant for existing designs and legacy systems. The device features four independent inputs/outputs (nY0, nY1, nY2, and nY3) and a common input/output (nZ) for each switch, along with a digital enable input (E) and two digital select inputs (S1 and S2) that are common to both switches.
