Product Details 74HC4067PW,118 is a 16-channel analog multiplexer and demultiplexer designed for selecting and routing analog or digital signals within electronic systems. The device integrates a single-pole 16-throw switching architecture, allowing one common signal terminal to be connected to one of sixteen independent channels according to the state of four digital select inputs.The device provides sixteen independent input/output channels, a common input/output terminal and four digital selection inputs. An enable input allows the complete switch network to be disabled when required. This structure makes the device useful when multiple signal sources need to share a common signal path while reducing the number of interface connections required by the host system.74HC4067PW,118 supports a wide supply-voltage range from 2V to 10V. The 74HC logic architecture uses CMOS-level control inputs, allowing the device to interface with appropriate digital controllers while maintaining low static power consumption.The four select inputs provide sixteen possible channel combinations. By applying the appropriate binary selection code, the host controller can connect the common terminal to one selected channel. This makes the device suitable for sequentially scanning multiple sensors, analog sources or measurement points with a single ADC or signal-processing path.The analog switch structure can handle both analog and digital signals within the supported operating conditions. Typical uses include analog multiplexing and demultiplexing, digital signal routing and signal gating. The device also features break-before-make switching behavior, helping prevent two channels from being connected to the common terminal simultaneously during channel transitions.The switch has a typical on-resistance of approximately 80Ω at a 4.5V supply according to the device family specifications, with the exact resistance varying with supply voltage and operating conditions. Nexperia documentation also specifies low power dissipation and high noise immunity for the 74HC4067 family.For higher-frequency signal-routing requirements, the device family provides useful switching performance within its specified electrical conditions. The current Nexperia listing shows the 74HC4067PW,118 in a 24-TSSOP package with a maximum on-resistance of 120Ω, 45ns maximum turn-on and turn-off times, and an operating temperature range of -40°C to +125°C.The 24-pin TSSOP package provides a compact surface-mount solution for circuit boards where sixteen signal channels need to be controlled from a digital interface. The package includes the sixteen switch terminals, four selection inputs, enable control, common terminal, supply and ground connections.74HC4067PW,118 can be used in sensor interface circuits where multiple analog sensors share one ADC input, as well as in measurement equipment, test systems and embedded controllers that need to select one signal from several available sources. It can also be used for digital signal routing when multiple logic signals need to share a common connection.The device is particularly useful for applications where PCB space and controller I/O resources need to be managed efficiently. Instead of dedicating a separate input path to every signal source, the multiplexer allows multiple channels to be sequentially connected to a shared signal-processing circuit.When designing with 74HC4067PW,118, engineers should verify the signal voltage range, on-resistance, signal current, channel capacitance, switching timing, control-input levels and source/load impedance according to the application. Analog signal accuracy can be affected by the switch resistance and parasitic capacitance, so these parameters should be considered when the device is used for precision measurement or higher-frequency signals.
