TIBPAL16R4-25CFN

Overview

The TIBPAL16R4-25CFN is a low-power high-performance Impact PAL circuit featuring registered outputs. It operates with a maximum propagation delay of 25 ns from inputs to outputs and 20 ns from the clock edge to registered outputs. The device supports a maximum clock frequency of 30 MHz and functions within a supply voltage range of 4.75 V to 5.25 V. It utilizes Advanced Low-Power Schottky technology.

Feature Summary

• Combines high-speed logic performance with low power consumption using Advanced Low-Power Schottky technology.
• Includes registered outputs that automatically set high during power-up for simplified state-machine initialization.
• Offers functional equivalency to legacy PAL devices while providing faster switching speeds.

Applications

• Complex digital logic replacement in industrial control systems
• State machine implementation in communication equipment
• Address decoding and bus interface logic in embedded systems

Procurement Notes

Verify component authenticity through authorized Texas Instruments distributors or certified third-party vendors. Confirm the package marking matches the specified PLCC configuration. Check for RoHS compliance status as indicated in the packaging data. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this device when designing circuits requiring registered output capabilities with guaranteed power-on reset states. Choose the CFN package variant for surface-mount applications needing compact board space. Ensure the design environment stays within the 0°C to 75°C operating temperature range defined for the C suffix series.

Part Context

This component belongs to the TIBPAL16 family of programmable logic devices manufactured by Texas Instruments. It is part of the Impact PAL series, which serves as a modernized successor to older standard PAL architectures. The family includes variants with different output configurations such as combinatorial and registered types.

Replacement Considerations

Publicly confirmed substitutes include other members of the TIBPAL16R4 series with different speed grades or package options, such as TIBPAL16R4-30MFKB for military temperature ranges. Verify pin compatibility and electrical characteristics before substituting with non-TI generic PAL equivalents.
