The TIBPAL22V10-7C is a programmable array logic device featuring high speed and functional equivalency
when compared to presently available devices. The TIBPAL22V10-7C is implemented with the familiar
sum-of-products (AND-OR) logic structure featuring programmable output logic macrocells. This IMPACT-X™
circuit combines the latest Advanced Low-Power Schottky technology with proven titanium-tungsten fuses to
provide reliable, high-performance substitutes for conventional TTL logic.
This device contains up to 22 inputs and 10 outputs. It incorporates the unique capability of defining and
programming the architecture of each output on an individual basis. Outputs can 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.
These devices are covered by U.S. Patent 4,410,987.
IMPACT-X is a trademark of Texas Instruments Incorporated.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
