PAL16R6-5JC

Overview

The Vantis PAL16R6-5JC is a high-speed Programmable Array Logic (PAL) device featuring a mixed output architecture. It provides ten dedicated inputs and six registered outputs, utilizing a 20-pin Plastic Leaded Chip Carrier (PLCC) package. The component operates with a maximum propagation delay of 5 nanoseconds and supports a maximum clock frequency of 200 MHz. Designed for TTL logic compatibility, it functions within a standard 5V supply voltage range. The device integrates power-up reset functionality and register preload capabilities to ensure reliable system initialization.

Feature Summary

• Mixed output configuration with 10 inputs and 6 registered outputs
• High-speed performance with 5ns propagation delay and 200MHz max clock rate
• Integrated power-up reset and register preload features
• TTL-compatible logic levels in a 20-pin PLCC package

Applications

• High-speed digital state machine implementations
• Complex address decoding logic
• Bus control and arbitration circuits
• Timing generation and synchronization modules

Procurement Notes

Verify the specific manufacturer source, as Vantis assets were acquired by Lattice Semiconductor. Confirm that the component meets current environmental compliance standards, noting that older PAL devices may not be RoHS compliant. Ensure the 20-pin PLCC package matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a fast, registered PAL solution with mixed output types is required. The 5ns speed class suits applications demanding low latency. Verify that the 10-input/6-output pinout aligns with the design constraints. Consider the availability of programming tools compatible with legacy PAL architectures if field programmability is needed.

Part Context

This part belongs to the classic PAL16R6 family, originally defined by Monolithic Memories and later produced by National Semiconductor and Vantis. The series represents a standard in simple programmable logic, offering a balance of flexibility and speed. Vantis manufactured these devices prior to the consolidation of PAL technology into larger CPLD families.

Replacement Considerations

Direct replacements include the AMD/AMD PAL16R6-5JC or the National Semiconductor TIBPAL16R6-5JC. For modern equivalents, consider Lattice GAL16V8 or similar CPLDs, though pinouts and logic density may differ. Verify electrical characteristics and package dimensions when substituting.
