PALC16R6

Cypress PALC20 Series devices are high- speed electrically programmable and UV- erasable logic devices produced in a proprietary N-well CMOS EPROM process. PALC16R6 utilize a sum-of-products (AND-OR) structure providing users with the ability to program custom logic functions serving unique requirements.

PALs PALC16R6 are offered in 20-pin plastic and ceramic DIP, plastic SOJ, and ceramic LCC packages. The ceramic package can be equipped with an erasure window; when exposed to UV light, the PAL is erased and can then be reprogrammed.

Before programming, AND PALC16R6 gates or product terms are connected via EPROM cells to both true and complement inputs.

Programming an EPROM cell disconnects an input term from a product term. Selective programming of PALC16R6 allows a specific logic function to be implemented in a PALC device.

PALC PALC16R6 devices are supplied in four functional configurations designated 16R8, 16R6, 16R4, and 16L8. These 8 devices have potentially 16 inputs and 8 outputs configurable by the user of PALC16R6. Output configurations of 8 registers, 8 combinatorial, 6 registers and 2 combinatorial as well as 4 registers and 4 combinatorial are provided by the 4 functional variations of the product family.
