CD4514BM

CD4514BM is a CMOS logic circuits dynamic type chip, and the product suite of Texas Instruments. This chip is used in logic-signal switches, multiplexers, or decoders. So what specific application field and working principle of this IC chip? Let\'s take a closer look.

The primary application of CD4514BM is to serve as BCD-to-decimal decoder/driver. It was designed to convert a BCD (Binary-Coded Decimal) code into a full 9-bit decimal code. Generally alternative 4-line BCD code is used, but it is sometimes converted from asynchronous parallel information source of another BCD code. A 28-pin DIP package (Dual In-line Package) usually contains two separate decoders and drivers sections. Each section can be used as a separate BCD-to-decimal or parallel-to-serial converter. Other popular application cases include antenna switching and digital decoding.

To better understand the working principle of CD4514BM, let\'s introduce how basic BCD to Decimal Converter works. BCD is a number representation that is used in digital circuits. Each 4-bit BCD represents one decimal digit. This is different from the 4-bit binary number that only represents the values 0 to 9. The CD4514BM works as an input signal line monitor and output logic circuit. BCD is provided as inputs to the logic circuit, and the outputs are set according to the BCD inputs. In instances where it is used as a BCD-to-decimal converter, the output of each section will drive the segment driver, LED, or other output devices.

The CD4514BM can also be used as a parallel-to-serial converter. When used in this way, the data is shifted into serially by using the serial clock inputs. The data is shifted out Q0 to Q15 depending on the inputs. The outputs can be assigned as the serial output data, or it can be assigned to an address decoder that can be used to select an input line. The device also has outputs that can be used to indicate the last bit of the serial output.

Overall CD4514BM is a logic-signal switches, multiplexers, decoders that offers universal accuracy, low power consumption, and good noise immunity. It can perform fast and properly in three application fields, including antenna switching, BCD-to-decimal decoder/driver and parallel-to-serial converter. With such a number of benefits, CD4514BM is often utilized in low-power, low-noise and other specialized applications.
