Overview
The 74HC4852D-Q100,118 is a dual single-pole quad-throw (SP4T) analog switch produced by Nexperia USA Inc. This component is designed for use in both analog and digital 4:1 multiplexer/demultiplexer applications. It features two independent switches, each with four inputs/outputs (nY0, nY1, nY2, and nY3) and a common input/output (nZ). The device includes 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. This device is notable for its injection-current effect control, which allows signals at disabled analog input channels to exceed the supply voltage without affecting the signal of the enabled analog channel.
