Overview
The 74HCT4067PW,112 is a 16-channel analog multiplexer/demultiplexer produced by Nexperia USA Inc. This component is part of the 74HC/74HCT family and is designed as a single-pole 16-throw analog switch (SP16T), making it suitable for both analog and digital 16:1 multiplexer/demultiplexer applications. The device features four digital select inputs (S0, S1, S2, and S3), sixteen independent inputs/outputs (Yn), a common input/output (Z), and a digital enable input (E). When the enable input (E) is HIGH, the switches are turned off. The component also includes clamp diodes to protect the inputs, allowing the use of current limiting resistors to interface with voltages exceeding VCC.
