PAL22V10-7PC

Overview

The PAL22V10-7PC is a high-performance Complex Programmable Logic Device (CPLD) belonging to the GAL16V8/PAL22V10 family. Manufactured by Vantis, this component features 22 general-purpose input/output pins and supports up to 10 registered outputs. It utilizes a 7ns propagation delay speed grade, suitable for digital logic applications requiring fast switching speeds. The device operates within a standard voltage range and is housed in a 24-pin PDIP package, providing a compact solution for replacing discrete TTL logic in embedded systems.

Feature Summary

• 22 General Purpose I/O Pins with flexible macrocell configuration
• 7ns maximum propagation delay for high-speed logic operations
• Up to 10 registered outputs supporting synchronous design styles
• 24-pin Plastic Dual In-line Package (PDIP) for through-hole mounting

Applications

• Discrete logic replacement in industrial control panels
• Address decoding and memory interface logic in legacy computer systems
• State machine implementation in automated testing equipment
• Signal buffering and protocol conversion in communication interfaces

Part Context

This component is part of the classic PAL/GAL logic family, originally developed by Lattice Semiconductor before being transferred to Vantis. It serves as a direct drop-in replacement for older PAL22V10 devices from various manufacturers, maintaining pin compatibility while offering updated manufacturing processes. It bridges the gap between simple discrete gates and modern FPGA technologies.

Replacement Considerations

When substituting this part, verify that the new component matches the 7ns speed grade. Ensure the programming tool supports the specific fuse map of the PAL22V10 architecture. Physical pinout compatibility must be confirmed if replacing units from different original equipment manufacturers.
