PAL16R4B-4MW/883B

Programmable Logic Device Pld Overview

The PAL16R4B-4MW/883B is a high-performance, military-grade Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices. It belongs to the PAL16R4 family and features a 20-pin ceramic dual in-line package (CDIP). The component operates on standard TTL logic levels and provides eight registered outputs with dedicated clock inputs. Designed for harsh environments, it meets MIL-STD-883 requirements, ensuring reliability through hermetic sealing and radiation hardness suitable for aerospace and defense applications.

Programmable Logic Device Pld Feature Summary

• Military-grade qualification compliant with MIL-STD-883 standards
• High-speed 4ns propagation delay for critical timing applications
• Hermetic ceramic dual in-line package (CDIP) for environmental protection
• Eight registered outputs with individual clock control

Programmable Logic Device Pld Applications

• Aerospace flight control systems requiring radiation tolerance
• Defense communication equipment operating in extreme temperatures
• Military-grade data acquisition and signal processing units
• Spacecraft telemetry and command logic circuits

Programmable Logic Device Pld Part Context

This part is a specific variant of the PAL16R4 series, distinguished by its 'B' suffix indicating military temperature range and '/883B' denoting compliance with MIL-STD-883 Method B testing. Unlike commercial equivalents, this version undergoes rigorous screening for particle impact noise sensitivity (PINS) and burn-in to guarantee long-term stability in mission-critical hardware.

Programmable Logic Device Pld Replacement Considerations

Direct replacements must match the military specification and hermetic packaging. Commercial PAL16R4 variants lack the required radiation hardness and thermal stability. Verify that substitute components meet the same MIL-STD-883 test methods and maintain identical pinout compatibility.
