CD4543BNS

Display Drivers Overview

The CD4543BNS is a CMOS BCD-to-7-segment latch/decoder/driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and features a propagation delay of 400 ns. The device supports four input lines and seven output lines, housed in a SOIC-16 surface-mount package. It functions across an extended temperature range from -55 °C to +125 °C.

Display Drivers Feature Summary

• Converts binary-coded decimal inputs into seven-segment display signals
• Integrates internal latching capability for data retention

Display Drivers Applications

• Seven-segment LED numeric displays
• LCD driver circuits
• Digital instrumentation readouts

Display Drivers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure the component matches the required operating temperature range and voltage parameters for your design. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and current availability status.

Display Drivers Selection Notes

Select this component when a dedicated BCD-to-seven-segment decoder with integrated latching is required. It is suitable for designs needing wide voltage operation and high noise immunity typical of CMOS logic families. Consider the SOIC-16 package constraints for PCB layout and thermal management requirements.

Display Drivers Part Context

This device belongs to the CD4500B series of CMOS logic components. It serves as a specialized interface between digital control systems and visual output devices. The series is characterized by low power consumption and compatibility with standard logic levels.

Display Drivers Replacement Considerations

Check for pin-compatible alternatives such as the CD4543BM or CD4543BMT if different packaging options are needed. Verify functional equivalence before substituting.
