• Features common-drain outputs optimized for direct connection to LCD segments

Display Drivers Applications

• Seven-segment LCD display systems
• Industrial control panel indicators
• Consumer electronics with numeric readouts

Display Drivers Procurement Notes

Verify that the specific order matches the MC14543BDR2G suffix to ensure the correct SOIC-16 surface-mount packaging and tape-and-reel delivery format. Confirm compliance with RoHS directives and AEC-Q100 automotive qualification requirements if the application demands high reliability or environmental stress screening. Ensure the procurement channel provides official datasheets to validate the manufacturer source and part authenticity before finalizing purchase agreements.

Display Drivers Selection Notes

Select this component when a BCD-to-seven-segment decoding function with integrated latching is required for LCD interfaces. The wide supply voltage range of 3 V to 18 V allows compatibility with various logic families and power rails. The extended temperature range up to +125 °C makes it suitable for harsh industrial environments. Consider the common-drain output structure for appropriate drive strength matching against the specific LCD segment load characteristics.

Display Drivers Part Context

This device belongs to the MC14543B family of CMOS logic circuits, specifically engineered as a decoder driver for alphanumeric displays. It serves as a standard interface between microcontroller BCD outputs and visual indication elements. The DR2G suffix indicates the specific tape-and-reel packaging variant within the broader MC14543 product line, distinguishing it from tube-packaged equivalents like the MC14543BDG.
