74HCT4051 is a single-pole octal-throw analog switch (SP8T) suitable for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch 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). When E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Technical data: Adapted to work with analog and digital signals 8 channels, 3 control inputs Supply voltage: 2-10V Analog input voltage range: -5~5V Enable input Pin pitch: 2.54 mm Suitable for contact plates https://elecena.pl/product/25280112/74hc4051-8-channel-mux-analog-multiplexer-module 2024-02-05 https://elecena.pl/product/25280112/74hc4051-8-channel-mux-analog-multiplexer-module 2025-10-29
