The GAL16VP8, with 64 mA drive capability and 15 ns maximum

propagation delay time is ideal for Bus and Memory control appli-

cations.

Semiconductor's advanced E

CMOS with Electrically Erasable (E

speed erase times (<100ms) allow the devices to be reprogrammed

quickly and efficiently.

System bus and memory interfaces require control logic before

driving the bus or memory interface signals. The GAL16VP8

combines the familiar GAL16V8 architecture with bus drivers as

its outputs. The generic architecture provides maximum design flex-

ibility by allowing the Output Logic Macrocell (OLMC) to be con-

figured by the user. The 64mA output drive eliminates the need for

additional devices to provide bus driving capability.

Unique test circuitry and reprogrammable cells allow complete AC,

DC, and functional testing during manufacture. As a result, Lattice

Semiconductor delivers 100% field programmability and function-

ality of all GAL products. In addition, 100 erase/write cycles and

data retention in excess of 20 years are specified.
