CD4543BE, BCD-to-7 Segment Latch/Decoder/Driver, DIP-16, 3V-18V

The CD4543BE is a BCD-to-7 segment latch/decoder/driver, designed for use in digital displays and numerical readout applications. It converts binary-coded decimal (BCD) inputs into standard 7-segment display outputs, making it ideal for electronic meters, frequency counters, and embedded digital systems. Operating within a voltage range of 3V to 18V, the CD4543BE ensures compatibility with various power supply systems. The built-in latch function allows the display to retain the last input value without requiring constant updates, reducing processing load on the controlling circuit. With its high output drive capability, the CD4543BE can directly interface with common-cathode 7-segment displays, simplifying circuit design. Packaged in a DIP-16 format, it is well-suited for breadboard projects, through-hole PCB designs, and industrial digital display systems.
