CD4543 DIP BCD To 7-Segment Latch/Decoder/Driver with Phase Input

Product Description: CD4543 DIP BCD To 7-Segment Latch/Decoder/Driver with Phase Input

The CD4543 DIP BCD To 7-Segment Latch/Decoder/Driver with Phase Input is a CMOS-based integrated circuit designed to convert binary-coded decimal (BCD) inputs into a 7-segment display output. This versatile device can be used to control 7-segment LEDs or LCD displays in applications requiring numeric display functions, such as digital clocks, counters, and displays for embedded systems.

The CD4543 includes a BCD to 7-segment decoder, a latch for holding the BCD input, and a driver to drive the 7-segment display. The phase input allows the user to control the latch and data output timing, enabling synchronous and asynchronous display operations. The output is compatible with both common cathode and common anode displays, making it highly adaptable for a wide variety of applications.

The BCD inputs (0–9) are decoded into the corresponding segments of the 7-segment display, allowing the display to show digits from 0 to 9. The integrated latch holds the display value, ensuring the display is stable during updates. The driver circuit ensures that sufficient current is supplied to the display for bright and clear visual output.

Operating within a wide voltage range of 3V to 18V, the CD4543 is ideal for both low-voltage and standard logic systems. Built using CMOS technology, the IC provides low power consumption, making it a great choice for battery-powered devices, embedded systems, and digital display projects.
