Additional Details

The AMPAL20L10-20PC consists of an AND array that feeds into a fixed OR array with inverting outputs. It has 10 outputs, each capable of implementing a complex logic function. The device is programmed using a standard PAL programmer, and the fuse map is defined by the desired logic function. Its 20ns propagation delay ensures that it can operate in high-speed digital circuits without introducing significant delays. It is typically supplied in a 20-pin DIP (Dual In-line Package).

Being sourced from Rochester Electronics, this part ensures continued availability and avoids obsolescence issues often encountered with older electronic components. It provides designers with a reliable, pin-compatible alternative to original devices that may no longer be in production, making it ideal for legacy system maintenance and repair as well as for new designs seeking proven technology.
