... LASH Cypress Semiconductor Corporation Multiple Array Matrix High-Density EPLDs CY7C342B. This allows the designer to replace 50 or more TTL packages with just one MAX EPLD. The family comes in a range of densities, shown below. By standardizing on a few MAX building blocks, the designer can replace hundreds of different 7400 series part numbers currently used in most dig- ital systems ...
