description

The TIBPAL22V10 and TIBPAL22V10A are programmable array logic devices 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

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.

These devices are covered by U.S. Patent 4,410,987.
IMPACT is a trademark of Texas Instruments Incorporated.

description (continued)

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.

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 and TIBPAL22V10A offer 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 TIBPAL22V10C and TIBPAL22V10AC are characterized for operation from 0

C to 75

C. The

TIBPAL22V10AM is characterized for operation over the full military temperature range of 55

C to125

preload procedure for registered outputs (see Notes 2 and 3)

The output registers can be preloaded to any desired state during device testing. This permits any state to be
tested without having to step through the entire state-machine sequence. Each register is preloaded individually
by following the steps given below:

Step 1. With V

at 5 V and pin 1 at V

, raise pin 13 to V

IHH

Step 2. Apply either V

or V

to the output corresponding to the register to be preloaded.

Step 3. Pulse pin 1, clocking in preload data.
Step 4. Remove output voltage, then lower pin 13 to V

. Preload can be verified by observing the voltage level

at the output pin.

power-up reset

Following power up, all registers are reset to zero. The output level depends on the polarity selected during
programming. This feature provides extra flexibility to the system designer and is especially valuable in
simplifying state-machine initialization. To ensure a valid power-up reset, it is important that the rise of V

monotonic. Following power-up reset, a low-to-high clock transition must not occur until all applicable input and
feedback setup times are met.
