GAL20V8A-12LVC

Programmable Logic Device Pld Overview

The GAL20V8A-12LVC is a CMOS Electrically Erasable Programmable Logic Device (EEPLD) manufactured by National Semiconductor. It features a PAL-type architecture with 20 input lines and 8 output lines housed in a 28-pin LDCC plastic package. The device supports a maximum propagation delay of 12 ns, enabling operation at clock frequencies up to approximately 83 MHz. It operates within a standard voltage range and includes macrocell structures for flexible logic implementation.

Programmable Logic Device Pld Feature Summary

• MACROCELL architecture for flexible logic design

Programmable Logic Device Pld Part Context

This component belongs to the GAL20V8 family of EEPLDs, which succeeded earlier GAL20V8B EPROM-based devices by offering electrical erasure capabilities. National Semiconductor produced this variant before its acquisition by Texas Instruments, maintaining compatibility with the standard GAL20V8 pinout and logical structure.
