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

Product Description: CD4543 SOP BCD to 7-Segment Latch/Decoder/Driver with Phase Input

The CD4543 SOP BCD to 7-Segment Latch/Decoder/Driver with Phase Input is a CMOS integrated circuit designed to convert Binary Coded Decimal (BCD) input into a decoded output for a 7-segment display. This IC is perfect for applications where numeric display of BCD data is required, such as in digital clocks, counters, and measurement devices. The CD4543 not only decodes the BCD input but also includes a latch function and a phase input, providing flexibility in controlling when the display is updated or changed.

This BCD to 7-segment driver supports common-cathode 7-segment displays, meaning that it can directly drive the segments of the display. It has the ability to latch the BCD input, which allows the display to hold a digit until the input changes, ensuring stable output and eliminating flickering. Additionally, the phase input allows for control over the timing and sequencing of data latching, making it useful in systems where multiple digits need to be updated in a controlled manner.

With low power consumption, high-speed operation, and a compact SOP package, the CD4543 is ideal for space-constrained designs and applications requiring a reliable BCD to 7-segment display interface. It provides both the decoding and driving capabilities, simplifying the design of digital displays.

Key Features:

• BCD to 7-Segment Decoder/Driver: Converts 4-bit BCD input into the corresponding 7-segment display output, showing decimal digits (0-9).
• Latch Functionality: The latch ensures that the display holds the current digit until a new input is latched, providing stable output and eliminating unwanted flicker.
• Phase Input: Provides control over the timing of the data latching, allowing for synchronized updates of multiple 7-segment displays in sequence.
• Common-Cathode Display Compatibility: Can directly drive common-cathode 7-segment displays, making it ideal for many standard display applications.
• CMOS Technology: Offers low power consumption, high-speed operation, and excellent noise immunity, ideal for modern digital systems.
• Wide Voltage Range: Operates between 3V to 18V, making it compatible with a variety of logic systems.
• Compact SOP Package: Surface-mount design provides a space-efficient solution for high-density PCB layouts.
• Low Power Consumption: Suitable for battery-operated devices or low-power applications.
• Easy Integration: Simplifies the process of interfacing BCD data to 7-segment displays, reducing the need for additional decoding logic.

Applications:

• Digital Clocks and Meters: Ideal for applications like digital clocks, timers, and measuring instruments, where BCD data needs to be displayed on 7-segment displays.
• Counters: Perfect for use in digital counters or event counters that need to display numbers in decimal format.
• Embedded Systems: Widely used in embedded systems where BCD input needs to be converted to a readable display.
• Measurement Systems: Used in measurement devices that need to display numeric readings on a 7-segment display.
• Microcontroller Interfaces: Excellent for microcontroller projects where the microcontroller outputs BCD data and the IC converts it to a visible 7-segment display.
• Digital Indicators: Perfect for numeric digital indicators where real-time data needs to be presented clearly in decimal form.
• Signal Display and Diagnostics: Suitable for signal display applications in systems requiring visual indication of status codes or numeric values.
