Functional Description
The Cypress PALC22V10B is a CMOS second-generation
programmable logic array device. It is implemented with the
familiar sum-of-products (AND-OR) logic structure and a new
concept, the "Programmable Macrocell."
The PALC22V10B is executed in a 24-pin 300-mil molded DIP,
a 300-mil windowed cerDIP, a 28-lead square ceramic lead-
less chip carrier, a 28-lead square plastic leaded chip carrier,
and provides up to 22 inputs and 10 outputs. When the win-
dowed cerDIP is exposed to UV light, the 22V10B is erased
and can then be reprogrammed. The programmable macrocell
provides the capability of defining the architecture of each out-
put individually. Each of the 10 potential outputs may be spec-
ified as "registered" or "combinatorial." Polarity of each output
may also be individually
