• Display blanking for invalid input codes
• Direct driving capability for LCD segments

Display Drivers Applications

• Liquid-crystal display systems
• Seven-segment numeric readouts
• BCD code conversion interfaces

Display Drivers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and environmental compliance. Ensure the ordering information matches the required DIP-16 configuration and RoHS status before finalizing procurement orders.

Display Drivers Selection Notes

Select this component for applications requiring direct BCD input to drive seven-segment LCDs. Verify that the system voltage remains within the 3V to 18V operational limits. Confirm that the through-hole PDIP-16 package aligns with the target PCB layout requirements.

Display Drivers Part Context

This part belongs to the Texas Instruments CD4543B family of CMOS logic devices. It serves as a dedicated decoder driver for numeric displays, offering a pin-compatible alternative to legacy TTL drivers while maintaining low power consumption suitable for battery-operated or portable instrumentation.

Display Drivers Replacement Considerations

The datasheet identifies the CD40568 (with pin 7 tied to Vss) as a pin-for-pin replacement.
