PAL20R4-5JC

Programmable Logic Device Pld Overview

The PAL20R4-5JC is a Vantis programmable logic device belonging to the OT PLD family. It utilizes a PAL-type architecture with TTL input compatibility and features registered output functions. The component is housed in a PQCC package with 28 terminals, supporting up to 16 inputs and 4 outputs. It operates at a nominal supply voltage of 5 V and exhibits a maximum propagation delay of 5 ns, enabling a maximum clock frequency of 200 MHz. The device is designed for through-hole or surface-mount applications depending on specific variant configurations, though this part number indicates a plastic quad flat pack configuration.

Programmable Logic Device Pld Feature Summary

• PAL-type architecture providing registered output functionality
• TTL-compatible input interface for standard logic integration
• High-speed operation with 5 ns propagation delay

Programmable Logic Device Pld Applications

• Complex digital logic implementation
• State machine design
• Address decoding circuits

Programmable Logic Device Pld Procurement Notes

Verify the exact package type and pinout against the official datasheet before procurement, as suffixes may indicate variations in temperature range or packaging style. Ensure the supplier provides documentation confirming the component matches the specified 5 ns delay and registered output characteristics. Cross-reference the manufacturer's current product status to confirm availability and compliance with relevant standards.

Programmable Logic Device Pld Selection Notes

Select this component when a registered PAL solution with fast switching speeds is required. The 5 ns delay suits high-frequency applications compared to slower variants. Consider the 28-pin PQCC package constraints for PCB layout. Verify input/output count requirements match the 16-in/4-out configuration before finalizing the design choice.

Programmable Logic Device Pld Part Context

This part belongs to the Vantis PAL series, a line of programmable logic devices. These components are designed to replace discrete logic gates, reducing board space and complexity. The PAL20R4-5JC specifically offers a balance of speed and I/O density within the PAL family, targeting applications requiring deterministic timing and registered outputs.

Programmable Logic Device Pld Replacement Considerations

Compatible substitutes include other PAL20R4 variants from Vantis with different speed grades, such as the PAL20R4-7JC or PAL20R4-10/2JC, provided the timing requirements allow for slower performance. Ensure the replacement maintains the same registered output architecture and package dimensions.
