PAL16R8B2CNL

Programmable Logic Device Pld Overview

The PAL16R8B-2CNL is a Programmable Array Logic (PAL) device manufactured by Vantis Corporation. It belongs to the PAL16R8 family, featuring an OT PLD architecture with TTL input compatibility and registered outputs. The component operates at a maximum clock frequency of 25 MHz with a propagation delay of 25 ns. It utilizes a 20-pin Plastic Quad Flatpack (PQFP) or similar surface-mount package variant, distinct from the PDIP20 version. The device requires a nominal 5 V power supply and supports standard industrial operating temperatures.

Programmable Logic Device Pld Feature Summary

• PAL-type architecture with 8 inputs and 8 registered outputs
• 25 ns propagation delay supporting up to 25 MHz clock frequency
• TTL-compatible inputs for direct logic interfacing
• Registered output function with power-up reset capability

Programmable Logic Device Pld Applications

• Digital state machine implementation
• Address decoding in memory systems
• Control logic for peripheral interfaces
• General-purpose registered I/O buffering

Programmable Logic Device Pld Part Context

This part is part of the PAL16R8 series, which provides 64 product terms for complex logic synthesis. The 'B' suffix typically denotes a specific speed grade or revision within the PAL16R8 family, while '2' indicates the 25 ns speed class. The 'CNL' suffix identifies the plastic quad flatpack package type. It serves as a drop-in replacement for older AMD/LSI Logic PAL16R8 devices in existing designs.

Programmable Logic Device Pld Replacement Considerations

Verify pinout compatibility with original PAL16R8 components. Ensure programming equipment supports the specific Vantis PAL architecture. Check that the registered output timing meets system requirements, as registered PALs introduce additional clock-to-output delays compared to combinatorial variants.
