Description
The GAL16V8/883 is a high performance E
2
CMOS program-
mable logic device processed in full compliance to MIL-STD-883.
This military grade device combines a high performance CMOS
process with Electrically Erasable (E
2
) floating gate technology to
provide the highest speed/power performance available in the
883 qualified PLD market. The GAL16V8D/883, at 7.5ns maxi-
mum propagation delay time, is the world's fastest military quali-
fied CMOS PLD.
The generic GAL architecture provides maximum design flexibil-
ity by allowing the Output Logic Macrocell (OLMC) to be config-
ured by the user. The GAL16V8/883 is capable of emulating all
standard 20-pin PAL
®
devices with full function/fuse map/para-
metric compatibility.
Unique test circuitry and reprogrammable cells allow complete
AC, DC, and functional testing during manufacture. Therefore,
Lattice Semiconductor delivers 100% field programmability and
functionality of all GAL products. In addition, 100 erase/write
cycles and data retention in excess of 20 years are specified.

1) The leakage current is due to the internal pull-up on all pins. See Input Buffer section for more information.
2) One output at a time for a maximum duration of one second. Vout = 0.5V was selected to avoid test problems caused by tester
ground degradation. Characterized but not 100% tested.
