PAL22V10-7JC

Overview

The PAL22V10-7JC is an EE PLD from Vantis Corporation, utilizing PAL-type architecture and CMOS technology. It features a propagation delay of 7.5 ns and operates at a maximum clock frequency of 40 MHz. The device supports TTL input levels and includes 12 dedicated inputs with 10 I/O lines, totaling 22 inputs and 10 outputs. It employs MACROCELL output functions within a PQCC28 plastic/epoxy package. The component is designed for surface mount applications and typically operates at a supply voltage of 5 V.

Feature Summary

• Supports high-speed logic implementation with a 7.5 ns propagation delay
• Integrates 12 dedicated inputs and 10 flexible I/O lines for versatile circuit design
• Utilizes MACROCELL output structures to enhance signal control capabilities

Applications

• Embedded logic replacement in industrial control systems
• Address decoding and bus interfacing in digital circuits
• State machine implementation for automated processes

Procurement Notes

Verify the manufacturer origin carefully, as Vantis assets were acquired by Lattice Semiconductor. Ensure the specific suffix matches the required speed grade and package type. Confirm RoHS compliance status if environmental regulations apply to your project. Request official datasheets to validate electrical characteristics against current standards before finalizing orders.

Selection Notes

Select this component when a fast TTL-compatible PLD is needed for moderate complexity logic. The 22-pin configuration offers a balance between pin count and board space. Consider the 7.5 ns delay for timing-critical paths. Evaluate alternative packages if surface mount constraints differ. Verify power supply requirements align with standard 5 V logic systems.

Part Context

This part belongs to the classic PAL22V10 series, widely used for general-purpose programmable logic. It serves as a direct replacement for older discrete gate designs. The family is known for reliability in legacy systems. Vantis was a primary supplier before industry consolidation. The device remains relevant for maintaining existing hardware infrastructure.

Replacement Considerations

Lattice GAL22V10C is a confirmed electrically compatible substitute. Check pinout compatibility during physical integration. Verify that the replacement maintains the same voltage and speed specifications.
