CD4543BPWR

Display Drivers Overview

The CD4543BPWR 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 package with surface-mount installation. 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 latching, decoding, and driving capabilities for LCD applications
• Supports wide supply voltage ranges suitable for various industrial environments

Display Drivers Applications

• Liquid-crystal display drivers
• Seven-segment numeric displays
• Industrial control panel indicators

Display Drivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package and tape-and-reel orientation. Confirm RoHS compliance status through official manufacturer documentation. Ensure the component matches the intended thermal and electrical specifications for the target application environment before finalizing procurement orders.

Display Drivers Selection Notes

Select this component when a latch/decoder/driver combination is required for BCD-to-seven-segment conversion. The wide voltage range allows compatibility with diverse power systems. Verify that the TSSOP-16 package fits the PCB layout constraints and that the propagation delay meets the system timing requirements.

Display Drivers Part Context

This part is part of the CD4543B family, which includes variants like CD4543BE and CD4543BMG4. These devices are designed for driving liquid-crystal displays and other seven-segment indicators. The family shares core functional characteristics but differs in packaging and manufacturing revisions.

Display Drivers Replacement Considerations

Check for direct pin-compatible substitutes within the same logic family. Verify that any replacement maintains the same voltage ratings and package dimensions. Consult official substitution guides for confirmed equivalent parts.
