The TIBP AL22V10-10C 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 titaniumtungsten 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.
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.

HIGH-PERFORMANCE IMPACT-X PROGRAMMABLE ARRAY LOGIC CIRCUITS
SRPS015 – D3972, FEBRUARY 1992
description (continued)
Circuit design is enhanced by the addition of a synchronous set and an asynchronous reset product term. These
functions are common to all registers. When the synchronous set product term is a logic 1, the output registers
are loaded with a logic 1 on the next low-to-high clock transition. When the asynchronous reset product term
is a logic 1, the output registers are loaded with a logic 0. The output logic level after set or reset depends on
the polarity selected during programming. Output registers can be preloaded to any desired state during testing.
Preloading permits full logical verification during product testing.
With features such as programmable output logic macrocells and variable product term distribution, the
TIBPAL22V10-10C offers quick design and development of custom LSI functions with complexities of 500 to
800 equivalent gates. Since each of the ten output pins may be individually configured as inputs on either a
temporary or permanent basis, functions requiring up to 21 inputs and a single output or down to 12 inputs and
10 outputs are possible.
A power-up clear function is supplied that forces all registered outputs to a predetermined state after power is
applied to the device. Registered outputs selected as active-low power up with their outputs high. Registered
outputs selected as active-high power up with their outputs low.
A single security fuse is provided on each device to discourage unauthorized copying of fuse patterns. Once
blown, the verification circuitry is disabled and all other fuses will appear to be open.
The TIBPAL22V10-10C is characterized for operation from 0°C to 75°C.
