CD4543BPW

Display Drivers Overview

The CD4543BPW is a CMOS BCD-to-seven-segment latch/decoder/driver manufactured by Texas Instruments. It belongs to the 4500 logic series and features four input lines and seven output lines. The device is housed in a TSSOP-16 surface-mount package. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. The propagation delay is specified at 400 ns.

Display Drivers Feature Summary

• Converts binary-coded decimal inputs into seven-segment display signals
• Integrates internal latching capability for data retention
• Supports direct driving of liquid-crystal displays

Display Drivers Applications

• Liquid-crystal display driver circuits
• Seven-segment numeric display systems
• BCD decoding applications in industrial instrumentation

Display Drivers Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-16 package variant during procurement. Confirm RoHS compliance status through official datasheets or manufacturer notifications. Ensure the component source is authorized to avoid counterfeit risks, as this part may have end-of-life implications depending on current production status.

Display Drivers Selection Notes

Select this component when a latch function is required alongside BCD-to-seven-segment decoding. The wide supply voltage range allows compatibility with various logic levels. Verify that the TSSOP-16 package fits the PCB footprint constraints and thermal requirements of the target application design.

Display Drivers Part Context

This part is a member of the Texas Instruments CD45xx family, which utilizes standard CMOS technology. It serves as a dedicated decoder for numeric displays, eliminating the need for external logic gates. The BPW designation indicates a specific tape-and-reel or tube packaging option within the broader CD4543B product line.

Display Drivers Replacement Considerations

Check for CD4543BE or CD4543BMG4 equivalents if pin-compatible alternatives are needed. Verify package differences, as BE denotes PDIP and BMG4 denotes SOIC-16. Consult Texas Instruments for current availability and lifecycle status before substituting.
