PAL20R6-5PC

Programmable Logic Device Pld Overview

The PAL20R6-5PC is a Programmable Array Logic (PAL) device manufactured by Vantis, formerly part of the Lattice Semiconductor and AMD product lines. It features a BICMOS technology architecture housed in a 20-pin Plastic Dual In-line Package (PDIP). The component provides 12 dedicated inputs and 6 registered outputs, supporting up to 64 product terms for complex logic implementation. Electrical characteristics include a maximum propagation delay of 5 ns and an operating temperature range from 0°C to 70°C. The device includes power-up reset functionality and operates on a single 5V supply.

Programmable Logic Device Pld Feature Summary

• Architecture: PAL-type with 12 dedicated inputs and 6 registered outputs
• Technology: BICMOS process for high-speed performance
• Package: 20-pin PDIP (0.300 inch width)
• Speed: 5 ns maximum propagation delay

Programmable Logic Device Pld Applications

• Digital state machine control
• Address decoding logic
• Bus interface protocols
• Timing control circuits

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer origin as Vantis or its predecessor entities (AMD/Lattice) due to historical brand transitions. Confirm RoHS compliance status, as older PAL devices may not meet current environmental standards. Ensure the package type matches the specific suffix (PC indicates PDIP). Check for obsolescence notices from current distributors.

Programmable Logic Device Pld Selection Notes

Select this component when registered output logic is required with 12 input lines. Compare against PAL20R8 variants if additional outputs are needed. Verify voltage levels match standard 5V TTL/CMOS systems. Consider pin compatibility with existing PCB footprints designed for 20-pin DIP packages.

Programmable Logic Device Pld Part Context

This device belongs to the classic GAL/PAL family of programmable logic devices. It serves as a drop-in replacement for legacy AMD or Lattice parts with identical pinouts and logic functions. The '5' suffix denotes the 5 ns speed grade, while 'PC' specifies the plastic DIP package.

Programmable Logic Device Pld Replacement Considerations

Direct substitutes include PAL20R6-5LP (ceramic DIP) or equivalent GAL16V8/GAL20V8 derivatives if logic capacity allows. Verify functional equivalence with PAL20RA6 variants if asynchronous resets are required. Cross-reference with Lattice P22 series for modern equivalents.
