Overview
The TIBPAL20X10-20CNT is a PAL-type programmable logic device manufactured by Texas Instruments. It features 20 inputs and 10 outputs, supporting up to 40 product terms with combinatorial output functions. The component operates on a 5 V power supply and utilizes a ceramic DIP-24 package. It is rated for an extended temperature range from -55 °C to 125 °C, ensuring reliability in demanding environments.
Feature Summary
- Supports complex custom logic implementation via programmable macrocells
- Utilizes robust ceramic packaging for enhanced durability
- Designed for high-temperature industrial operation
Applications
- Digital logic function replacement
- Interface adaptation circuits
- Combinatorial logic generation
Procurement Notes
Verify the specific suffix 'CNT' against official Texas Instruments documentation to confirm the exact package variant and material composition. Ensure that the procurement channel provides traceability for the ceramic DIP-24 form factor. Confirm compliance status regarding RoHS directives as indicated in manufacturer specifications before finalizing acquisition.
Selection Notes
Select this component when a fixed-function PAL solution is required for combinatorial logic with 20 inputs and 10 outputs. Consider the 20ns propagation delay and 5V TTL compatibility for system integration. Evaluate the extended temperature range suitability for the intended operational environment compared to standard commercial grade alternatives.
Part Context
This part belongs to the TIBPAL series of simple programmable logic devices. It serves as a hardware implementation alternative to discrete gate arrays, offering reduced board space and improved signal integrity for digital designs requiring specific logical operations defined at the time of programming.
Replacement Considerations
Direct substitutes include the TIBPAL20X10-30CNT, which shares the same pinout and logic architecture but offers a different speed grade. Verify electrical compatibility and package dimensions when cross-referencing with other PAL-type devices from the same family.
