description
These programmable array logic devices feature
high speed and functional equivalency when
compared with currently available devices. 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. 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.

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 TIBPAL20’ C series is characterized from 0°C to 75°C. The TIBPAL20’ M series is characterized for
operation over the full military temperature range of −55°C to 125°C.

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 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.
Step 2.
Step 3.
Step 4.
With VCC at 5 volts and Pin 1 at VIL, raise Pin 13 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 13 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.

B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 2
is for an output with internal conditions such that the output is high except when disabled by the output control.
C. All input pulses have the following characteristics: For C suffix, use the voltage levels indicated in parentheses ( ). PRR ≤ 1 MHz,
tr = tf ≤ 2 ns, duty cycle = 50%. For M suffix, use the voltage levels indicated in brackets [ ]. PRR ≤ 10 MHz, tr and tf ≤ 2 ns, duty cycle
= 50%.
D. When measuring propagation delay times of 3-state outputs, switch S1 is closed.
E. Equivalent loads may be used for testing.
