Overview
The HEF4051BTT-Q100,11 is a high-performance 8-channel analog multiplexer/demultiplexer produced by Nexperia USA Inc. This component is a single-pole octal-throw analog switch (SP8T) designed for use in both analog and digital 8:1 multiplexer/demultiplexer applications. It features three digital select inputs (S1, S2, and S3), eight independent inputs/outputs (Yn), a common input/output (Z), and a digital enable input (E). The switch is turned off when the enable input (E) is HIGH. The device includes clamp diodes on the inputs, allowing the use of current limiting resistors to interface with voltages exceeding VCC.
