Cypress Semiconductor PAL22V10
PALC22V10 is a CMOS second-generation programmable logic array device. When the windowed cerDIP is exposed to UV light, the 22V10 is erased and can then be reprogrammed. The programmable macrocell provides the capability of defining the architecture of each output Document #: 38-00020-H individually.FEATURES
● Advanced second-generation PAL architecture● Low power — 55 mA max. “L” — 90 mA max. standard — 120 mA max. military
● CMOS EPROM technology for reprogrammability
● Variable product terms — 2 x (8 through 16) product terms
● User-programmable macrocell — Output polarity control — Individually selectable for registered or combinatorial operation
