CD4511BD/3

Display Drivers Overview

The CD4511BD/3 is a CMOS BCD-to-7-segment decoder/driver from the 4000/14000/40000 series, manufactured by Harris Corporation. It features true outputs and is housed in a 16-pin ceramic dual in-line package (CDIP). The device operates within a temperature range of -55 °C to 125 °C and includes specific functional attributes such as a blanking input, lamp test input, and an output high current capability of 10 mA at a voltage of 3.9 V.

Display Drivers Feature Summary

• Includes dedicated inputs for display blanking and lamp testing functions
• Provides direct drive capability for LED displays with specified output current characteristics
• Features latched input control for stable data retention

Display Drivers Applications

• Driving LED displays via dedicated driver interface
• Military-grade electronic systems requiring extended temperature operation
• Ceramic-packaged logic circuits in harsh environments

Display Drivers Procurement Notes

Verify component authenticity against manufacturer records due to potential legacy status. Confirm compliance requirements as the specific unit is marked non-RoHS. Ensure the ceramic DIP-16 package matches the design constraints. Validate that the military temperature rating aligns with system specifications before integration.

Display Drivers Selection Notes

Select this component when a hermetically sealed ceramic package is required for reliability. The wide operating temperature range supports extreme environmental conditions. Verify that the 10 mA output current meets the load requirements of the connected display segments without external buffering.

Display Drivers Part Context

This part belongs to the standard 4000-series CMOS logic family produced by Harris Corporation. It serves as a specialized interface between binary-coded decimal logic and visual output devices. The ceramic construction distinguishes it from plastic variants, targeting applications where radiation hardness or thermal stability is critical.

Display Drivers Replacement Considerations

Direct substitutes include other manufacturers' CD4511 variants in ceramic packages, such as those from Renesas or Texas Instruments, provided they match the military temperature grade and pinout compatibility.
