• • Pins 1, 9: Power supply voltage
• • Pins 2, 10: Input A
• • Pins 3, 11: Input B
• • Pins 4, 12: Output 0
• • Pins 5, 13: Output 1
• • Pins 6, 14: Output 2
• • Pins 7, 15: Output 3
• • Pins 8, 16: Ground

Working Principle

The working principle of the CD40117BNSRG4 is based on the BCD code. BCD code is a numerical representation method in which each decimal digit is encoded with 4 bits. The CD40117BNSRG4 decodes the BCD code as binary coded decimal (BCD). The input voltage is applied to the input pins, A and B. The voltage is then decoded into binary outputs. The decoder identifies each binary code sequence as a valid BCD code, and the corresponding decimal digit is output from the output pins.

When the input is logic low, the corresponding output is logic low. When the input is logic high, it is decoded into the corresponding decimal digit. When more than one code is logic high, the last one is taken as valid and other outputs are disregarded. This makes decoding simple and reliable.

The CD40117BNSRG4 is a simple and reliable BCD-to-Decimal Decoder. It is used for a variety of applications, including driving seven-segment displays, encoding and decoding BCD data, and generating asynchronous reset signals. It can be used in various logic systems, as it is available in a variety of standard logic packages.
