The TIBPAL22V10-20M is a programmable array logic device featuring high speed and functional equivalency
when compared to presently available devices. They are implemented with the familiar sum-of-products
(AND-OR) logic structure featuring the new concept “Programmable Output Logic Macrocell”. These
IMPACT-X™ circuits combine the latest Advanced Low-Power Schottky technology with proven titanium-
tungsten fuses to provide reliable, high-performance substitutes for conventional TTL logic.
These devices contain up to 22 inputs and 10 outputs. They incorporate the unique capability of defining and
programming the architecture of each output on an individual basis. Outputs may be registered or nonregistered
and inverting or noninverting as shown in the output logic macrocell diagram. The ten potential outputs are
enabled through the use of individual product terms.
Further advantages can be seen in the introduction of variable product term distribution. This technique
allocates from 8 to 16 logical product terms to each output for an average of 12 product terms per output. This
variable allocation of terms allows far more complex functions to be implemented than in previously available
devices.
This device is covered by U.S. Patent 4,410,987.
