5408/BDA

Overview

The Rochester Electronics LLC 5408/BDA is a dual 4-input AND gate integrated circuit belonging to the 5400 series of military-grade logic devices. Manufactured using ceramic flatpack technology, this component provides robust performance for high-reliability applications. It features two independent logic channels, each accepting four inputs to produce a single output when all inputs are high. The device is designed to operate within a wide temperature range and supports standard voltage supplies typical of the 5400 series, ensuring compatibility with legacy military and aerospace systems requiring hardened logic components.

Feature Summary

• Military-grade reliability with ceramic flatpack construction
• Dual independent 4-input AND logic channels
• Wide operating temperature range suitable for harsh environments

Applications

• Aerospace avionics control systems
• Military communication equipment
• High-reliability industrial automation

Procurement Notes

Verify the specific suffix and manufacturer origin carefully, as Rochester Electronics often sources these parts from original manufacturers or other authorized distributors. Confirm the package type matches your existing footprint requirements. Check for any lot traceability documentation if required by your quality management system. Ensure the device meets the specific military grade standards expected for your application environment.

Selection Notes

Select this component when military-grade radiation hardness and thermal stability are critical. The ceramic package offers superior hermeticity compared to plastic alternatives. Consider the pin count and layout constraints of the flatpack package during PCB design. Verify that the input voltage levels align with your system's logic family specifications before integration.

Part Context

This part falls under the broader category of 5400 series logic ICs, which are standardized for military use. Rochester Electronics specializes in lifecycle management for obsolete and hard-to-find semiconductors. This specific model represents a discrete logic function commonly used in digital circuit design for decision-making processes within larger systems.

Replacement Considerations

Direct replacements may include equivalent parts from other manufacturers offering military-grade 5400 series AND gates. Verify pinout compatibility and electrical characteristics such as propagation delay and power consumption. Ensure the replacement maintains the same package style or requires an adapter.
