A20576 - PALC22V10D-15JC Reprogrammable CMOS PAL Device (Cypress)

The PALC22V10D-15JC is a CMOS second-generation programmable logic array device. It is implemented with a sum-of-products (AND-OR) logic structure and another concept, the "programmable macrocell." The PALC22V10D-15JC provides up to 22 inputs and 10 outputs, has a frequency (max) of 83.3MHz and an operating supply voltage (Typ) of 5V. When the windowed cerDIP is exposed to UV light, the PALC22V10D-15JC is erased and can then be reprogrammed. The programmable macrocell provides the capability of defining the architecture of each output individually. Each of the 10 potential outputs may be specified as registered or combinatorial. Polarity of each output may also be individually selected, allowing complete flexibility of output configuration. Further configurability is provided through array-configurable output enable for each potential output. This feature allows the 10 outputs to be reconfigured as inputs on an individual basis, or alternately used as a combination I/O controlled by the programmable array.
