TM USE ULTRA37000 FOR ALL NEW DESIGNS PALCE20V8 Flash-Erasable Reprogrammable CMOS PAL Device QSOP package available Features 10, 15, and 25 ns coml version Active pull-up on data input pins 15, and 25 ns military/industrial versions Low power version (20V8L) High reliability 55 mA max. commercial (15, 25 ns) Proven Flash technology 65 mA max. military/industrial 100% programming and functional testing (15, 25 ns) Standard version has low power Functional Description 90 mA max. commercial The Cypress PALCE20V8 is a CMOS Flash Erasable (15, 25 ns) second-generation programmable array logic device. It is 115 mA max. commercial (10 ns) implemented with the familiar sum-of-product (AND-OR) logic 130 mA max. military/industrial (15, 25 ns) structure and the programmable macrocell. CMOS Flash technology for electrical erasability and The PALCE20V8 is executed in a 24-pin 300-mil molded DIP, reprogrammability a 300-mil cerdip, a 28-lead square ceramic leadless chip carrier, a 28-lead square plastic leaded chip carrier, and a User-programmable macrocell 24-lead quarter size outline. The device provides up to 20 Output polarity control inputs and 8 outputs. The PALCE20V8 can be electrically erased and reprogrammed. The programmable macrocell Individually selectable for registered or combina- enables the device to function as a superset to the familiar torial operation 24-pin PLDs such as 20L8, 20R8, 20R6, 20R4.
