PAL20R4-10/2JC

Programmable Logic Device Pld Overview

The PAL20R4-10/2JC is an Electrically Erasable Programmable Logic Device (EE PLD) manufactured by Vantis Corporation. It features a CMOS technology with a propagation delay of 10 ns and supports a maximum clock frequency of 71.4 MHz. The device operates at a nominal supply voltage of 5 V and includes 14 dedicated inputs and 8 I/O lines, totaling 28 terminals. Packaged in a square plastic epoxy chip carrier (PQCC28), it is designed for commercial temperature ranges from -40 °C to 70 °C. The architecture utilizes macrocell output functions, providing a flexible solution for digital logic implementation within surface-mount applications.

Programmable Logic Device Pld Feature Summary

• CMOS EE PLD architecture with 10 ns propagation delay
• 14 dedicated inputs and 8 bidirectional I/O lines
• 28-pin Quad Flat Package (PQCC28) suitable for surface mount
• Operates on 5 V supply with commercial temperature rating

Programmable Logic Device Pld Applications

• Digital logic replacement for standard TTL/CMOS gates
• Address decoding and control logic in embedded systems
• Interface bridging between different logic families

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer designation as Vantis Corporation or its predecessor entities when sourcing. Confirm the package type matches the PQCC28 specification and ensure the operating temperature range meets commercial requirements. Check for RoHS compliance status if required by specific assembly standards, as original documentation may list qualification status differently.

Programmable Logic Device Pld Selection Notes

Select this component when a low pin-count PLD with registered outputs is needed. The 14-input configuration allows for complex combinational logic reduction. Ensure the design accommodates the 5 V logic levels and that the PCB layout supports the J-bend terminal form factor of the PQCC28 package for proper reflow soldering.

Programmable Logic Device Pld Part Context

This part belongs to the PAL20V8/PAL20R4 family of EE PLDs, which bridge the gap between traditional PALs and modern CPLDs. Unlike volatile PALs, these devices retain configuration without power. The 'R' suffix typically indicates registered outputs, while 'V' denotes combinatorial outputs, offering flexibility in state machine design compared to fixed-function logic.

Programmable Logic Device Pld Replacement Considerations

Direct substitutes include other PAL20R4 variants from Lattice Semiconductor or Microchip Technology, provided they match the 28-pin PQCC package and 10 ns speed grade. Verify pin compatibility and electrical characteristics before substitution.
