GAL16V8A-15LVC

Programmable Logic Device Pld Overview

The GAL16V8A-15LVC is a CMOS-based Generic Array Logic (GAL) device manufactured by National Semiconductor, now part of Texas Instruments. It belongs to the GAL16V8 family and features a 20-pin Plastic Leaded Chip Carrier (PLCC) package. The component operates with a single 5V supply and provides eight output macrocells capable of implementing complex logic functions. Key electrical characteristics include a maximum propagation delay of 15 ns and a typical operating current of 75 mA. The device supports active pull-ups on all pins and offers reconfigurable logic capabilities with high-speed electrical erasure.

Programmable Logic Device Pld Feature Summary

Programmable Logic Device Pld Procurement Notes

Verify manufacturer origin as National Semiconductor or Texas Instruments due to acquisition history. Confirm package type is PLCC-20 plastic. Check for lead-free compliance status as original specifications may indicate non-compliance with modern RoHS standards. Ensure sourcing from authorized distributors to avoid counterfeit components.

Programmable Logic Device Pld Selection Notes

Select this component when replacing GAL16V8 variants requiring 15 ns speed grade. Compare pin compatibility with other GAL16V8 derivatives if footprint constraints exist. Consider power dissipation requirements given the 75 mA typical current draw. Verify voltage tolerance matches system 5V logic levels.

Programmable Logic Device Pld Part Context

This device is part of the GAL16V8 series, which emulates 20-pin PAL devices with full function and fuse map compatibility. The '15' suffix indicates the 15 ns speed grade, while 'LVC' denotes the PLCC package variant. National Semiconductor's GAL line was designed to offer reprogrammability over one-time programmable fuses.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements include GAL16V8B-15LVC and GAL16V8D-15LVC from Lattice Semiconductor. Verify electrical parameters match before substitution. Cross-reference datasheets for timing differences between manufacturers.
