PAL20R6BCNL

Programmable Logic Device Pld Overview

The PAL20R6BCNL is a Programmable Array Logic (PAL) device manufactured by Vantis. It features an OT PLD architecture with TTL input compatibility and a maximum propagation delay of 25 ns. The component utilizes a 28-pin Plastic Quad Chip Carrier (PQCC) package, specifically identified as LCC-28, with dimensions of 0.451 x 0.451 inches. Electrical specifications include a maximum operating temperature of 75 °C. The logic structure comprises 10 dedicated inputs and 2 I/O lines, supporting mixed output functions within a 5 V supply environment.

Programmable Logic Device Pld Feature Summary

• PAL-type architecture with 25 ns propagation delay
• 28-pin PQCC/LCC-28 plastic chip carrier package
• 10 dedicated inputs and 2 I/O lines
• Mixed output function capability

Programmable Logic Device Pld Applications

• Digital logic replacement in legacy systems
• State machine implementation
• Address decoding circuits

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer origin, as Vantis acquired assets from AMD and Monolithic Memories. Confirm the specific suffix 'BCNL' corresponds to the commercial temperature range and lead-free or non-RoHS status as defined in the original datasheet. Ensure the 28-pin QCCJ package footprint matches the target PCB design.

Programmable Logic Device Pld Selection Notes

Select this part for applications requiring 10 inputs and registered outputs with a 25 ns speed grade. Compare against the PAL20R6ACNL for pinout and electrical equivalence. Verify that the mixed output configuration meets the system's drive requirements and that the 5 V logic levels are compatible with the surrounding circuitry.

Programmable Logic Device Pld Part Context

This component belongs to the PAL20 family of programmable logic devices. It shares architectural similarities with the PAL20R6ACNL but may differ in manufacturing source due to the transition from AMD to Vantis. The device is part of the broader PAL series used for fixed-function logic replacement.

Programmable Logic Device Pld Replacement Considerations

Direct replacements include the PAL20R6ACNL from AMD or equivalent parts from National Semiconductor such as the PAL20X6VM, provided the package and timing specifications are verified.
