MC14543BDG

Display Drivers Overview

The MC14543BDG is a BCD-to-seven-segment latch decoder driver manufactured by onsemi, belonging to the MC14543B series. It operates within a supply voltage range of 3 V to 18 V and supports surface-mount installation in an SOIC-16 package. The device features a single circuit configuration with a maximum power dissipation of 500 mW. It functions effectively across an extended temperature range from -55 °C to +125 °C, providing reliable decoding performance for LCD applications.

Display Drivers Feature Summary

• Converts binary-coded decimal inputs into seven-segment outputs suitable for driving LCD displays
• Integrates latching capability to maintain output states independently of input changes
• Supports wide operating voltage ranges compatible with standard logic levels

Display Drivers Applications

• BCD to seven-segment decoding for liquid crystal displays
• Digital display drivers requiring latch functionality
• Consumer electronics instrumentation panels

Display Drivers Procurement Notes

Verify the specific suffix BDG confirms the SOIC-16 surface mount package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration. Ensure thermal management strategies account for the specified 500 mW power dissipation limit under worst-case operating conditions.

Display Drivers Selection Notes

Select this component when a dedicated latch decoder is required for LCD interfaces rather than simple combinational logic. The integrated latch feature simplifies control logic by holding segment data stable. Verify that the target application requires the specific pinout and electrical characteristics defined for the MC14543B series compared to non-latching alternatives.

Display Drivers Part Context

This part belongs to the MC14543B family of BCD-to-seven-segment decoders produced by onsemi. It is categorized under encoders, decoders, multiplexers, and demultiplexers within the standard product portfolio. The device serves as a fundamental interface component between digital control circuits and visual output devices.

Display Drivers Replacement Considerations

Consult official cross-reference lists for equivalent parts from other manufacturers. Verify pin compatibility and logical function equivalence before substituting.
