CD4543BNSR

Display Drivers Overview

The CD4543BNSR is a CMOS BCD-to-7-segment latch/decoder/driver from the Texas Instruments 4500 logic series. It features four input lines and seven output lines, packaged in a surface-mount SOIC-16 format. The device operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. 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
• Designed for direct driving of common-anode displays

Display Drivers Applications

• Seven-segment digital display systems
• Numeric readout interfaces
• Consumer electronic instrumentation panels

Display Drivers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure environmental compliance requirements match project standards. Confirm that the SOIC-16 footprint aligns with PCB layout constraints before finalizing procurement orders.

Display Drivers Selection Notes

Select this component when a dedicated decoder with integrated latching is required for BCD applications. Consider the wide voltage tolerance and extended temperature range for industrial environments. Evaluate propagation delay characteristics against system timing requirements.

Display Drivers Part Context

This part belongs to the CD4500B family of high-voltage CMOS logic devices. It serves as a specialized decoder within the broader category of encoders, decoders, multiplexers, and demultiplexers offered by Texas Instruments for general-purpose logic applications.
