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. 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.
