description
These programmable array logic devices feature
high speed and functionality similar to the
TIBPAL 1GL8, 16R4, 16R6, 16R8 series, but
with the added advantage of D-type transparent
latches on the inputs. If any input register is not
desired, it can be converted to an input buffer
by simply programming the architectural fuse.
Combining Advanced Low-Power Schottky t
technology, with proven titanium-tungsten
fuses, these devices will provide reliable high
performance substitutes over conventional TTL
logic. Their easy programmability allows for
quick design of custom functions and typically
result in a more compact circuit board. In
addition, chip carriers are available for further
reduction in board space.
Extra circuitry has been provided to allow loading
of each register asynchronously to either a high
or low state. This feature simplifies testing
because the registers can be set to an initial state
prior to executing the test sequence.
An M suffix designates full-temperature circuits
that are characterized for operation over the full
military temperature range of - 55 DC to 125 DC.
A C suffix designates commercial-temperature
circuits that are characterized for operation from
ODC to 70 D C.
