Overview
The 74HC4067DB, produced by NXP Semiconductors (now part of Nexperia), is a single-pole 16-throw analog switch (SP16T) designed for use in both analog and digital 16:1 multiplexer/demultiplexer applications. This component is part of the 74HC and 74HCT series, known for their high performance and versatility in various electronic systems.
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 inclusion of clamp diodes allows for the use of current limiting resistors to interface inputs to voltages exceeding VCC.
