CD4543 BCD to 7-Segment Decoder – Datasheet

The CD4543BE is a BCD-to-seven Segment Latch/Decoder/Driver, designed primarily for liquid-crystal display (LCD) applications. The CD4543 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. CD4543 has integral importance in DLD design and logic switching applications.

BCD to 7-Segment Decoder

A BCD to Seven Segment decoder is a combinational logic circuit that accepts a decimal digit in BCD (input) and generates appropriate outputs for the segments to display the input decimal digit.

CD4543 Key Features
