Overview
The 74HCT4051D/AUJ is a high-speed CMOS analog multiplexer/demultiplexer integrated circuit produced by NXP USA Inc. This component is designed as a single-pole octal-throw analog switch (SP8T), making it suitable for both analog and digital 8:1 multiplexer/demultiplexer applications. It features three digital select inputs (S0, S1, and S2), eight independent inputs/outputs (Yn), a common input/output (Z), and a digital enable input (E). The device is particularly useful for logic level translation, allowing 5 V logic to communicate with ±5 V analog signals.
