GAL16V8A-15LVI

Programmable Logic Device Pld Overview

The GAL16V8A-15LVI is a CMOS-based Generic Array Logic (GAL) device manufactured by National Semiconductor. It features an EE PLD architecture with 16 inputs and 8 outputs, housed in a 20-pin LDCC package. The component operates at a maximum clock frequency of 45.5 MHz with a propagation delay of 15 ns. It utilizes E²CMOS technology for electrical erasure and reprogramming, offering high performance and low power consumption compared to bipolar PAL devices.

Programmable Logic Device Pld Feature Summary

• EE PLD Architecture: Electrically erasable and reprogrammable logic device using E²CMOS technology.
• I/O Configuration: Supports 16 input lines and 8 output lines within a 20-pin LDCC plastic package.
• Performance Specifications: Maximum clock frequency of 45.5 MHz and typical propagation delay of 15 ns.
• PAL Compatibility: Emulates standard 20-pin PAL devices with full function and fuse map compatibility.

Programmable Logic Device Pld Applications

• Digital logic replacement for legacy bipolar PAL devices.
• Complex combinational and registered logic implementation.

Programmable Logic Device Pld Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, following the corporate acquisition. Confirm the specific suffix 'LVI' corresponds to the LDCC-20 plastic package and commercial temperature range. Ensure the device meets required RoHS compliance standards if applicable to the target assembly process.

Programmable Logic Device Pld Selection Notes

Select this component when replacing obsolete GAL16V8 variants requiring 15 ns speed. Compare against Lattice GAL16V8B series for pin-compatible alternatives. Verify that the 8-output macrocell structure meets the logic density requirements. Check voltage supply specifications to ensure compatibility with the system's 5V logic levels.

Programmable Logic Device Pld Part Context

This part belongs to the GAL16V8 family of Simple Programmable Logic Devices (SPLDs). It serves as a drop-in replacement for older bipolar PAL16V8 components. The device allows field reprogramming, distinguishing it from one-time programmable fuses found in standard PALs. It represents a transition technology between fixed logic gates and modern CPLDs.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible substitutes include the Lattice GAL16V8B-15LP and GAL16V8D-15LJI. Verify electrical parameters such as propagation delay and power consumption match the original design constraints before substitution.
