The Cypress PALC22V10B is a CMOS second-generation
15 ns commercial and industrial programmable logic array device. It is implemented with the
10 ns t familiar sum-of-products (AND-OR) logic structure and a new
CO
concept, the Programmable Macrocell.

a 300-mil windowed cerDIP, a 28-lead square ceramic
50 MHz
leadless chip carrier, a 28-lead square plastic leaded chip
