Overview
The 74LV4051PW/AUJ, produced by Nexperia (formerly NXP USA Inc.), is an 8-channel analog multiplexer/demultiplexer. This device is designed for low-voltage applications and is pin and function compatible with the 74HC4051 and 74HCT4051. It features three digital select inputs (S0 to S2) and an active-LOW enable input (E), along with eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). The device operates within a supply voltage range of 1.0 V to 6.0 V, making it suitable for a variety of low-voltage applications.
