The CD74HC4543EE4 is an integrated circuit (IC) component that belongs to the family of high-speed CMOS logic devices. It is a BCD-to-seven-segment latch/decoder/driver designed to convert binary-coded decimal (BCD) input data into seven-segment display outputs for numerical representation. This versatile component offers several key features that make it useful in various applications.
One of the prominent features of the CD74HC4543EE4 is its ability to accept BCD input data, which consists of four binary inputs, and convert it to a seven-segment output. This conversion process involves decoding the BCD data and driving the corresponding segments of a seven-segment display to represent the decimal value.
Another important feature of this IC component is its latch functionality. The CD74HC4543EE4 possesses four input latches that allow data to be latched and remain stable until new data is received. This feature proves beneficial when synchronizing the BCD inputs with a clock signal, ensuring accurate and reliable data transmission.
The CD74HC4543EE4 is designed to operate at high speeds, making it suitable for applications that require rapid data processing and display refresh rates. With a speed of up to 177 MHz, this IC component can handle demanding tasks without compromising performance.
Additionally, this IC includes built-in protection features such as diode clamping and resistors to prevent damage caused by electrostatic discharge (ESD)
