Functional Features
The CD4048BPW is a binary to octal 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, E2, E3) control the operation of the decoder. When all enable inputs are high, the decoder is enabled and the selected output is determined by the binary input. The outputs are active low, meaning they are inverted versions of the desired output.
Advantages and Disadvantages
Advantages: - High-speed operation - Low-power consumption - Wide operating voltage range - Compact PDIP package for easy integration
Disadvantages: - Outputs are active low, requiring additional inversion circuitry if active high outputs are desired - Limited to 3-bit binary input, limiting the number of possible combinations
Working Principles
The CD4048BPW works based on the principle of binary decoding. It uses a combination of logic gates to decode the binary input and select the appropriate output. The enable inputs control the operation of the decoder, enabling or disabling the selection process. The selected output is determined by the binary input combination.
Application Field Plans
The CD4048BPW can be used in various applications that require binary to octal decoding or demultiplexing. Some potential application fields include:
- Address decoding in microprocessors and microcontrollers
