Functional Features

• The SN74AHC158DBR is a 2-input to 1-output multiplexer.
• It selects one of the two input signals based on the select inputs (S0 and S1).
• The output signal (Y) represents the selected input signal.
• The enable input (OE#) controls the output state.

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Wide supply voltage range - Small package size

Disadvantages: - Limited number of input channels - Not suitable for complex multiplexing applications

Working Principles

The SN74AHC158DBR uses CMOS technology to achieve high-speed operation and low power consumption. It consists of a combination of logic gates that perform the multiplexing function. The select inputs determine which input signal is passed through to the output. The enable input controls the output state, allowing it to be enabled or disabled as needed.
