• Flexible Architecture: Configurable Output Logic Macrocells (OLMCs) supporting simple, complex, and registered modes.
• PAL Emulation: Compatible with standard 20-pin PAL fuse maps and parametric specifications.
• Low Power Consumption: Quarter-power version draws approximately 45 mA typical supply current.

Programmable Logic Device Pld Applications

• DMA Control
• State Machine Control
• High Speed Graphics Processing

Programmable Logic Device Pld Procurement Notes

All devices in the GAL16V8 series have been officially discontinued per Product Change Notification PCN#13-10. No new production units are available from Lattice Semiconductor. Verification of component authenticity and condition is critical when sourcing from secondary markets due to the end-of-life status.

Programmable Logic Device Pld Selection Notes

This specific part number denotes the Industrial grade (-I), Quarter power (-Q), 15 ns speed grade (-15), and Plastic Leadless Chip Carrier package (-J). Designers requiring active procurement should evaluate modern Lattice SPLD or FPGA alternatives that offer equivalent pin counts and logic density with current manufacturing support.

Programmable Logic Device Pld Part Context

The GAL16V8D series represents a generation of generic array logic devices designed to replace hardwired TTL/CMOS logic. The 'D' suffix indicates the use of E2CMOS technology, distinguishing it from earlier fuse-based GAL16V8C devices. This architecture allows for field reconfigurability without UV erasure.

Programmable Logic Device Pld Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Due to the discontinued status, direct pin-to-pin functional equivalents from other manufacturers may require schematic review to ensure compatibility with OLMC configurations and timing requirements.
