Overview
The 74HCT4052D,112 is a dual single-pole quad-throw (SP4T) analog switch, part of the 74HCT4052 series produced by Nexperia USA Inc. This component is designed for use in both analog and digital 4:1 multiplexer/demultiplexer applications. 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 (S0 and S1) that are common to both switches. When the enable input (E) is HIGH, the switches are turned off. The device includes clamp diodes on the inputs, allowing the use of current limiting resistors to interface inputs to voltages beyond VCC.
