description  
The TIBPAL22VP10’ is equivalent to the  
TIBPAL22V10A but offers additional flexibility in  
the output structure. The improved output  
macrocell uses the registered outputs as inputs  
when in a high-impedance condition. This  
provides two additional output configurations for a  
total of six possible macrocell configurations all of  
which are shown in Figure 1.  
NC No internal connection  
Pin assignments in operating mode  
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. In addition, the data may be fed back into the array from either the register or the  
I/O port. 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.  
These devices are covered by U.S. Patent 4,410,987.

description (continued)  
PROGRAMMABLE ARRAY LOGIC CIRCUITS  
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  
TIBPAL22VP10’ 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 TIBPAL22V10-20C is characterized for operation from 0°C to 75°C. The TIBPAL22V10-25M is  
characterized for operation over the full military temperature range of –55°C to 125°C.

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  
CC  
IL  
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

PROGRAMMABLE ARRAY LOGIC CIRCUITS  
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  
be

programming information  
Texas Instruments programmable logic devices can be programmed using widely available software and  
inexpensive device programmers.  
When the additional fuses are not being used, the TIBPAL22VP10 can be programmed using the  
TIBPAL22V10/10Aprogramming algorithm. The fuse configuration data can either be from a JEDEC file (format  
per JEDEC Standard No. 3-A) or a TIBPAL22V10/10A master.

IMPORTANT NOTICE  
Texas Instruments (TI) reserves the right to make changes to its products or to discontinue any semiconductor  
product or service without notice, and advises its customers to obtain the latest version of relevant information  
to verify, before placing orders, that the information being relied on is current.  
TI warrants performance of its semiconductor products and related software to the specifications applicable at  
the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are  
utilized to the extent TI deems necessary to support this warranty. Specific testing of all parameters of each  
device is not necessarily performed, except those mandated by government requirements.  
Certain applications using semiconductor products may involve potential risks of death, personal injury, or  
severe property or environmental damage (“Critical Applications”).  
TI SEMICONDUCTOR PRODUCTS ARE NOT DESIGNED, INTENDED, AUTHORIZED, OR WARRANTED  
TO BE SUITABLE FOR USE IN LIFE-SUPPORT APPLICATIONS, DEVICES OR SYSTEMS OR OTHER  
CRITICAL APPLICATIONS.  
Inclusion of TI products in such applications is understood to be fully at the risk of the customer. Use of TI  
products in such applications requires the written approval of an appropriate TI officer. Questions concerning  
potential risk applications should be directed to TI through a local SC sales office.  
In order to minimize risks associated with the customer’s applications, adequate design and operating  
safeguards should be provided by the customer to minimize inherent or procedural hazards.  
TI assumes no liability for applications assistance, customer product design, software performance, or  
infringement of patents or services described herein. Nor does TI warrant or represent that any license, either  
express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property
