Functional Features

  • CD74HC139M96 is a high-speed CMOS decoder/demultiplexer IC.
  • It consists of two independent 2-to-4 line decoders in a single package.
  • The active LOW enable inputs (E1 and E2) control the operation of each decoder.
  • The binary inputs (A0, A1, B0, B1) determine which output line(s) will be activated.
  • The outputs (Y0, Y1, Y2, Y3) are active LOW.

Advantages and Disadvantages

Advantages: - High-speed operation - Wide operating voltage range - Compact size with multiple decoders in a single package - Active LOW enable inputs provide flexibility in controlling the decoders

Disadvantages: - Limited number of output lines (four in total) - Not suitable for applications requiring more than four output lines

Working Principles

CD74HC139M96 operates based on the principle of decoding binary inputs into corresponding output lines. The active LOW enable inputs allow the user to selectively activate one or both decoders. The binary inputs determine which output line(s) will be activated, based on the combination of input values.
