CD4511BK3

Display Drivers Overview

The CD4511BK3 is a CMOS BCD-to-7-segment decoder/driver manufactured by Harris Corporation. It features a true output configuration designed for direct LED display driving within the 4000/14000/40000 series logic family. The device operates on a single power supply ranging from 3V to 18V and supports an extended industrial temperature range of -55°C to 125°C. It utilizes a 16-pin Ceramic Dual In-line Package (CDIP) with metal-sealed cofired construction. Key functional inputs include latch, blanking, and lamp test controls.

Display Drivers Feature Summary

• Provides direct decoding of Binary-Coded Decimal inputs into seven-segment displays
• Includes dedicated control inputs for data latching, display blanking, and lamp testing
• Constructed using hermetically sealed ceramic packaging for environmental protection

Display Drivers Applications

• Driving common-anode LED numeric displays in industrial instrumentation
• BCD-to-decimal conversion circuits requiring high noise immunity
• Military or aerospace electronic systems necessitating wide temperature operation

Display Drivers Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers. Confirm that the package matches the specified 16-pin CDIP form factor. Ensure compliance with project requirements regarding RoHS status, as this specific variant may not meet current environmental directives. Validate supplier documentation against the manufacturer's official datasheet specifications before procurement.

Display Drivers Selection Notes

Select this component when a hermetically sealed package is required for harsh environments. It is suitable for applications needing robust BCD decoding with integrated display driver capabilities. Consider the operating voltage range and temperature specifications to ensure compatibility with the system's power supply and thermal constraints. Verify pinout alignment with existing PCB layouts.

Display Drivers Part Context

This part belongs to the Harris Corporation 4000-series CMOS logic family, known for high noise immunity and wide supply voltage ranges. The CD4511BK3 variant specifically denotes the ceramic dual in-line package version, distinguishing it from plastic or surface-mount equivalents within the same logical function set.

Display Drivers Replacement Considerations

Compatible substitutes include the CD4511BDMSH and CD4511BDMSR, which share identical logical functions and pinouts but differ in package material or reel configuration.
