Functional Features

• CD74HC151MG4 is an 8-to-1 multiplexer with a single output (Y) and eight inputs (A0-A7).
• The selection of the input signal to be routed to the output is controlled by three select lines (B, C, D).
• It operates on a wide supply voltage range of 2V to 6V, making it compatible with various digital systems.
• The propagation delay of 13 ns ensures fast switching between input signals.
• The CMOS logic design provides low power consumption and high noise immunity.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient signal routing in digital circuits. - Wide supply voltage range enables compatibility with different systems. - Low power consumption makes it suitable for battery-powered devices. - CMOS technology provides high noise immunity.

Disadvantages: - Limited to 8 input signals, which may not be sufficient for complex applications requiring more inputs. - Propagation delay may introduce timing issues in certain high-frequency applications.

Working Principles

CD74HC151MG4 works based on the principle of digital multiplexing. It selects one of the eight input signals based on the control inputs (B, C, D) and routes it to the output (Y). The selection is determined by the binary value applied to the control inputs. The selected input signal appears at the output with minimal delay.
