GAL16V8D-25QPN

Programmable Logic Device Pld Overview

The GAL16V8D-25QPN is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor. It utilizes E2CMOS technology to provide Electrically Erasable and Programmable logic within a 20-pin PLCC package. The device features 16 inputs and 8 outputs, with a maximum propagation delay of 25 ns and a typical operating supply current of 45 mA for the Quarter Power variant. It supports three Output Logic Macrocell modes: registered, complex, and simple, allowing flexible emulation of standard PAL architectures.

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification PCN#13-10. No new production units are available from Lattice Semiconductor. Verification of authenticity is critical when sourcing from third-party distributors due to the end-of-life status. Designers should plan for obsolescence management or migration to alternative devices.

Programmable Logic Device Pld Selection Notes

Select this part only for legacy system maintenance where specific pinouts and timing characteristics are required. The 'Q' suffix indicates Quarter Power consumption (approx. 45 mA), while 'PN' denotes a lead-free PLCC package. Ensure design software compilers support the GAL16V8 device type for proper OLMC configuration.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents a high-performance CMOS PLD family designed to replace discrete logic gates. The D-series variants offer improved speed and lower power compared to earlier C-series devices. This specific model belongs to the industrial/commercial grade lineup characterized by its 25 ns speed grade.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Discontinued devices typically require functional equivalents from other manufacturers or modern FPGA/SPLD families that match the I/O count and package constraints.
