TIBPAL20L8-10CFN Datasheet PDF - TI

●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.

●• High-Performance Operation:

●   fmax (no feedback)

●      TIBPAL20R’ . . . 71.4 MHz

●   fmax (internal feedback)

●      TIBPAL20R’ . . . 58.8 MHz

●   fmax (external feedback)

●      TIBPAL20R’ . . . 55.5 MHz

●   Propagation Delay

●      TIBPAL20’ . . . 10 ns Max

●• Functionally Equivalent, but Faster Than Existing 24-Pin PLD Circuits

●• Preload Capability on Output Registers Simplifies Testing

●• Power-Up Clear on Registered Devices (All Register Outputs are Set Low, but Voltage Levels at the Output Pins Go High)

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

●• Security Fuse Prevents Duplication

●• Dependable Texas Instruments Quality and Reliability
