The CD4543 is a CMOS BCD-to-7 Segment Latch/Decoder/Driver IC designed to convert a 4-bit Binary Coded Decimal (BCD) input into the corresponding seven-segment display outputs. Originally developed for LCD applications, the IC can also drive LED, incandescent, gas-discharge, and fluorescent displays, making it a versatile display driver for digital electronics.

The IC integrates a 4-bit input latch, BCD-to-7 segment decoder, and display driver into a single package, reducing external circuitry and simplifying display interfacing. It features a display blanking function, a PHASE input that allows operation with both common-anode and common-cathode LED displays, and compatibility with CMOS, NMOS, and TTL logic families.

Operating over a wide supply voltage range of 3V to 18V, the CD4543 is widely used in digital clocks, counters, measurement instruments, industrial control systems, calculators, panel meters, and educational electronics projects.
