The TC74LCX138FT(EL) has a total of 16 pins:
The TC74LCX138FT(EL) is a 3-to-8 line decoder/demultiplexer IC. It takes a 3-bit binary input and selects one of the eight outputs based on the input combination. The enable inputs (E1 and E2) control the operation of the decoder/demultiplexer. When both enable inputs are high, the IC is enabled, and the selected output is determined by the address inputs (A0, A1, and A2).
Advantages: - Low-voltage operation allows for compatibility with various systems - High-speed operation enables quick decoding and demultiplexing - Low-power consumption reduces energy requirements
Disadvantages: - Limited to 3-bit input, restricting the number of possible combinations - Not suitable for applications requiring higher bit decoding or demultiplexing
The TC74LCX138FT(EL) works based on the principle of digital logic. The address inputs determine the desired output line by activating the corresponding combination of transistors within the IC. The enable inputs control the overall operation of the decoder/demultiplexer.
The TC74LCX138FT(EL) finds applications in various fields, including:
These alternative models offer similar functionality and can be used as substitutes for the TC74LCX138FT(EL) in various applications.
