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 TIBPAL20R4-15CNT is characterized from 0?C to 75?C.
Features:
High-Performance: fmax (w/o feedback) 45 MHz
High-Performance: 45 MHz Min
Reduced ICC of 180 mA Max
Functionally Equivalent, but Faster Than PAL20L8, PAL20R4, PAL20R6, PAL20R8
Power-Up Clear on Registered Devices (All Register Outputs are Set Low, but Voltage Levels at the Output Pins Go High)
Preload Capability on Output Registers Simplifies Testing
Datasheet Available:Texas Instruments TIBPAL20R4-15CNT
24 pin DIP. Manufactured by Texas Instruments.

A20339 - TIBPAL20R4-15CNT High-Performance Impact PAL Circuit (TI)
Detailed Description
These programmable array logic devices feature high speed and functional equivalency when compared with currently available devices. These IMPACTTM 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 further reduction in board space.Extra circuitry has been provided to allow loading of each register asynchronously to either a high or low state.
