CD4543 BCD to 7 Segment Decoder IC - DIP-16 Package

The CD4543 is a BCD to 7-segment decoder/driver IC designed for use with liquid crystal displays (LCDs). It converts 4-bit binary-coded decimal (BCD) input data into signals to drive 7-segment displays. The IC includes latch circuitry for storing the input data and provides phase and blanking control inputs for display flexibility. It is widely used in digital counters, clocks, and other applications where numeric displays are required.

Features of CD4543 BCD to 7 Segment Decoder IC:

1. Converts 4-bit BCD input to 7-segment output for LCD displays
2. Built-in latch enables data storage
3. Compatible with both common cathode and anode displays (via external components)
4. Blanking input controls display on/off
5. Phase input allows multiplexed LCD display driving
6. Wide supply voltage range and high noise immunity
7. DIP-16 through-hole package for easy prototyping
