• Impact PAL architecture for flexible logic programming
• Standard plastic/epoxy packaging for reliable mounting

Applications

• Digital logic circuit implementation
• System control logic replacement
• General-purpose programmable logic integration

Procurement Notes

Verify the exact manufacturer source when sourcing this legacy component, as availability may vary between original equipment manufacturer stock and third-party distributors. Confirm that the received unit matches the TIBPALT19R6CNT designation precisely, paying attention to any suffix variations that might indicate different temperature ranges or package styles. Ensure compatibility with existing 5V logic systems given the specified minimum supply voltage requirements.

Selection Notes

Select this component when a fixed-function PAL replacement is required for existing designs utilizing Texas Instruments Impact PAL circuits. Consider the 25 ns speed characteristic against system timing constraints. Evaluate the physical package dimensions and pinout configuration to ensure mechanical fit within the target PCB layout. Verify that the logic density meets the specific application's gate count requirements without unnecessary complexity.

Part Context

This device belongs to the Texas Instruments Impact PAL family, a series of programmable logic devices known for their versatility in replacing small-scale integration logic gates. These components were widely used in digital systems before the prevalence of complex FPGA technologies. The TIBPALT19R6CNT specifically addresses applications requiring moderate logic complexity with fast switching speeds.

Replacement Considerations

Direct substitutes include other parts from the TI Impact PAL series with equivalent pinouts and logic structures. Cross-reference with generic PAL equivalents only if electrical characteristics and pin assignments are identical. Verify that alternative sources maintain the same 25 ns performance specification.
