* Programmable Logic Device (PLD) IC Macrocells

General 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 further reduction in board space.

All of the registered outputs are set to a low level during power-up. In addition, 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 PAL20’M series is characterized for operation over the full military temperature range of -55°C to 125°C. The

PAL20’C series is characterized for operation from 0℃ to 75℃.

Features

• High Performance ... 35 MHz Min

• Preload Capability on Output Registers Simplifies Testing

• Power-Up Ciear on Registered Devices

• Package Options Include Both Plastic and Ceramic Chip Carriers in Addition to Plastic and Ceramic DIPs
