GAL 16V8 PDF

The GAL16V8, at ns maximum propagation delay time, combines a high performance CMOS process with Electrically Erasable (E2) floating gate technology. PURPOSE: In the past, we have used the fuse maps for the PAL16L8 and applied them to the file “” for the GAL16V8. Needhams Electronics wrote this file. GAL16V8 GAL16LV8C (V)8 Macrocells Features. HIGH PERFORMANCE E2CMOS® TECHNOLOGY ns Maximum Propagation Delay Fmax = MHz .
