description
These programmable array logic devices feature high speed and functional equivalency when compared with
currently available devices. 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. Their easy programmability allows for quick design of custom functions and typically
results in a more compact circuit board. In addition, chip carriers are available for futher reduction in board
space.
All of the register outputs are set to a low level during power-up. Extra circuitry has been provided to allow loading
of each register asynchronously to either a high or low state. This feature simplifies testing because the registers
can be set to an initial state prior to executing the test sequence.
The TIBPAL16’ C series is characterized from 0°C to 75°C. The TIBPAL16’ M series is characterized for
operation over the full military temperature range of –55°C to 125°C.
These devices are covered by U.S. Patent 4,410,987.
IMPACT-X is a trademark of Texas Instruments Incorporated.

programming information
Texas Instruments programmable logic devices can be programmed using widely available software and
inexpensive device programmers.
Complete programming specifications, algorithms, and the latest information on hardware, software, and
firmware are available upon request. Information on programmers capable of programming Texas Instruments
programmable logic is also available, upon request, from the nearest TI field sales office, local authorized TI
distributor, or by calling Texas Instruments at (214) 997-5666.
preload procedure for registered outputs (see Figure 1 and Note 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.
Step 2.
Step 3.
Step 4.
With VCC at 5 volts and Pin 1 at VIL, raise Pin 11 to VIHH.
Apply either VIL or VIH to the output corresponding to the register to be preloaded.
Pulse Pin 1, clocking in preload data.
Remove output voltage, then lower Pin 11 to VIL. Preload can be verified by observing the
voltage level at the output pin.

power-up reset (see Figure 2)
Following power up, all registers are reset to zero. 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 VCC be monotonic. Following power-up reset, a low-to-high clock transition must not
occur until all applicable input and feedback setup times are met.

fmax without feedback, see Figure 3
In this mode, data is presented at the input to the flip-flop and clocked through to the Q output with no feedback.
Under this condition, the clock period is limited by the sum of the data setup time and the data hold time (tsu + th).
However, the minimum fmax is determined by the minimum clock period (tw high + tw low).

This configuration is most popular in counters and on-chip state-machine designs. The flip-flop inputs are
defined by the device inputs and flip-flop outputs. Under this condition, the period is limited by the internal delay
from the flip-flop outputs through the internal feedback and logic array to the inputs of the next flip-flop.

fmax with external feedback, see Figure 5
This configuration is a typical state-machine design with feedback signals sent off-chip. This external feedback
could go back to the device inputs or to a second device in a multi-chip state machine. The slowest path defining
the period is the sum of the clock-to-output time and the input setup time for the external signals
(tsu + tpd CLK-to-Q).
