Description: 1. The 74HC151 is an 8-input, 1-output, analog multiplexer integrated circuit (IC) from the 74HCT/HCS/HCSC series. It allows selecting one input among eight available through a single control line. 2. Features: This IC operates on a +5V power supply and has a low power consumption of approximately 1 mW per chip at maximum switch rates. It offers a high input impedance (>10MΩ) to minimize loading effects on the signal sources. 3. Applications: The 74HC151 is commonly used in data acquisition systems, digital voltmeters, and control circuits where multiple sensors or channels need to be multiplexed for connection to a single output or measurement unit. 4. Operation: When the control input (A0-A2) of the IC is set, it connects the corresponding input line (IN1 to IN8) to the output line (OUT). Switching between inputs is done by changing the control line values. 5. Benefits: This IC provides isolation between the selected input and the other ones, which can help reduce noise and unwa
