CD4511BD3

Display Drivers Overview

The CD4511BD3 is a CMOS BCD-to-7-segment decoder/driver manufactured by Harris Corporation. It features true outputs designed for common-cathode LED displays. The device operates within a supply voltage range of 5V to 15V and supports a wide temperature range from -55°C to 125°C. It utilizes a 16-pin ceramic dual in-line package (DIP) with tin/lead terminal plating. Key functional inputs include blanking, lamp test, and latch control. The component is classified as military grade under MIL-STD-883 standards.

Display Drivers Feature Summary

• Provides direct decoding of binary-coded decimal inputs into seven-segment display signals
• Includes dedicated inputs for blanking and lamp testing functions
• Constructed using radiation-hardened CMOS technology suitable for harsh environments
• Features true output polarity optimized for common-cathode LED configurations

Display Drivers Applications

• Military-grade digital display systems requiring high reliability
• Avionics instrumentation panels operating in extreme temperatures
• Industrial control interfaces utilizing common-cathode LED readouts
• Spacecraft telemetry display units

Display Drivers Procurement Notes

Verify the specific suffix 'BD3' indicates the ceramic DIP variant with tin/lead plating. Confirm military qualification status against MIL-STD-883 requirements. Ensure compatibility with common-cathode LED arrays due to true output design. Check for RoHS non-compliance given the lead-based termination. Validate supplier authorization for Harris/Renesas legacy military components.

Display Drivers Selection Notes

Select this component when a radiation-tolerant BCD-to-7-segment decoder is required for critical applications. It is appropriate for designs needing operation across the full military temperature spectrum. Choose this part over plastic packages if hermetic sealing is mandated. Ensure the target display uses a common-cathode configuration to match the true output logic.

Display Drivers Part Context

This component belongs to the CD4000 series of CMOS logic devices produced by Harris Corporation, now part of Renesas Electronics. The CD4511 family specifically addresses the need for reliable numeric display drivers in aerospace and defense sectors. The 'BD3' designation typically denotes the ceramic package variant, distinguishing it from standard plastic DIP versions found in commercial electronics.
