PAL16L8B-4MW/883B

Programmable Logic Device Pld Overview

The PAL16L8B-4MW/883B is a high-speed Programmable Array Logic (PAL) device manufactured by Advanced Micro Devices. It belongs to the PAL16R8 family, designed for TTL logic replacement in high-performance applications. The component features a maximum propagation delay of 4 ns and operates within a military-grade temperature range. It utilizes a 20-pin ceramic flatpack package with hermetic sealing, indicated by the /883B suffix denoting MIL-PRF-38534 compliance. Key architectural characteristics include an OR plane with 16 inputs and 8 registered outputs, providing flexible combinational and sequential logic capabilities for digital system design.

Programmable Logic Device Pld Part Context

This part is a specific variant of the PAL16L8B from the PAL16R8 family. The '4' indicates the 4 ns speed grade, while '/883B' specifies the military reliability standard and package type. It serves as a programmable alternative to fixed-function TTL gates, offering design flexibility without sacrificing speed.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements may include other manufacturers' PAL16L8 devices with equivalent 4 ns speed grades. Verify voltage compatibility and package dimensions when substituting with non-MIL-spec versions.
