PAL20R8BCJS

Programmable Logic Device Pld Overview

The PAL20R8BCJS is a Programmable Array Logic (PAL) device manufactured by Vantis. It features an OT PLD architecture with TTL technology and a propagation delay of 15 ns. The component operates within a supply voltage range of 4.75 V to 5.25 V, with a nominal voltage of 5 V. It provides 8 dedicated inputs and registered outputs. The device is housed in a CDIP20 package, characterized by a ceramic, glass-sealed body and dual inline through-hole terminals. It supports a maximum clock frequency of 40 MHz and functions within a commercial extended temperature range.

Programmable Logic Device Pld Feature Summary

• OT PLD architecture with 8 dedicated inputs and registered outputs
• 15 ns propagation delay supporting up to 40 MHz clock frequency
• CDIP20 ceramic, glass-sealed package with dual inline terminals
• TTL technology compatible with 5 V nominal supply voltage

Programmable Logic Device Pld Applications

• Digital logic replacement for legacy PAL devices
• Registered output logic circuits requiring high-speed switching
• Industrial control systems operating in commercial extended temperature ranges

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer designation as Vantis or its predecessor entities, as historical lineage involves Monolithic Memories and AMD/Vantis. Confirm the specific suffix BCJS corresponds to the CDIP20 ceramic package and 15 ns speed grade. Ensure compatibility with existing programming equipment for PAL-type devices. Check for RoHS compliance status, as older TTL PLDs may not meet current environmental standards.

Programmable Logic Device Pld Selection Notes

Select this component when a registered output PAL with 8 inputs is required in a 20-pin ceramic DIP package. Compare against the PAL16R8 variants if fewer inputs are sufficient. Verify that the 15 ns delay meets system timing requirements. Consider the CDIP20 form factor for through-hole mounting constraints. Ensure the design software supports the specific PAL architecture for programming file generation.

Programmable Logic Device Pld Part Context

This device belongs to the PAL series of programmable logic devices produced by Vantis. It serves as a fixed-function logic solution where field-programmability is needed during manufacturing. The part number structure indicates the pin count, I/O configuration, speed grade, and package type. It is part of a broader family of PAL devices used for discrete logic integration before the widespread adoption of CPLDs.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include other PAL20R8 variants from different manufacturers such as National Semiconductor or Lattice, provided the electrical characteristics match. Verify that the replacement device offers registered outputs and similar propagation delays. Ensure the package footprint matches the CDIP20 specification.
