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 P ALC22V10B 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
provi des the capabi lity of defin ing the archit ecture of eac h out-
put indiv idually. Eac h of the 10 pot ential outp uts may be spec -
ified as “registered” or “combinatorial.” Polarity o f eac h o utp ut
may also be ind iv idu all y
