Overview
The 74LV4051PW/AU118 is an 8-channel analog multiplexer/demultiplexer produced by Nexperia, although it is often associated with NXP due to the historical connection between the two companies. This device is part of the low-voltage Si-gate CMOS family and is pin and function compatible with the 74HC4051 and 74HCT4051. It features three digital select inputs (S0 to S2), an active-LOW enable input (E), eight independent inputs/outputs (Y0 to Y7), and a common input/output (Z). The device operates with a supply voltage range of 1.0 V to 6.0 V, making it versatile for various low-voltage applications.
