TIBPAL20L10-30CFN

Overview

The TIBPAL20L10-30CFN is a complex programmable logic device (CPLD) manufactured by Texas Instruments. It features a PAL-type architecture with 20 inputs and 10 outputs, providing 40 product terms for logic implementation. The device operates on a single 5 V supply and exhibits a maximum propagation delay of 30 ns, supporting clock frequencies up to approximately 33 MHz. It is housed in a 28-pin plastic small outline package (SOIC). The component is designed for combinatorial logic applications within industrial temperature ranges.

Feature Summary

• PAL-type architecture with 20 inputs and 10 outputs
• 40 product terms for logic synthesis
• 30 ns maximum propagation delay
• Single 5 V power supply operation

Applications

• Combinatorial logic replacement
• Address decoding circuits
• Bus protocol translation

Procurement Notes

Verify the specific suffix 'CFN' against official Texas Instruments documentation to confirm the exact package type and temperature range. Ensure compliance with RoHS directives if required, as older PLD variants may not meet current environmental standards. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a simple PLD with 20 inputs and 10 outputs is required for combinatorial logic. The 30 ns speed grade suits moderate-speed digital designs. Compare with other TIBPAL series devices if higher pin counts or registered outputs are needed. Ensure the 5 V logic levels match the system voltage requirements.

Part Context

This part belongs to the Texas Instruments TIBPAL family of simple programmable logic devices. These components serve as drop-in replacements for standard TTL logic gates, offering design flexibility through programmable interconnect arrays. The TIBPAL series is widely used in legacy systems and industrial control applications requiring custom logic functions.

Replacement Considerations

Direct pin-compatible replacements include other TIBPAL20L10 variants with different speed grades or packages, such as TIBPAL20L10-30PCN. Verify electrical characteristics and package dimensions before substitution.
