TIBPAL16R8-12CN

Overview

The TIBPAL16R8-12CN is a high-performance Impact-X PAL circuit manufactured by Texas Instruments. It belongs to the SPLD category and features a 20-pin PDIP package with through-hole mounting. The device operates within a commercial temperature range of 0°C to 75°C and requires a supply voltage between 4.5V and 5.5V. It provides 12 dedicated inputs, 8 registered outputs, and supports a maximum clock frequency of approximately 83 MHz with a typical propagation delay of 12ns.

Feature Summary

• High-speed performance with 12ns typical propagation delay
• Registered output architecture with 8 macrocells
• Commercial temperature range operation (0°C to 75°C)
• Standard 5V TTL-compatible logic levels

Applications

• Digital state machine implementation
• Address decoding in memory systems
• Bus protocol control logic
• Timing signal generation

Procurement Notes

Verify component authenticity due to potential availability from secondary markets. Confirm package integrity and pin alignment for the 20-PDIP form factor. Check for RoHS compliance status as legacy PLDs may have varying environmental certifications depending on production batch.

Selection Notes

Select this part when registered outputs are required for synchronous design applications. Compare against TIBPAL16R8 variants with different speed grades or temperature ranges if system constraints differ. Ensure input count matches the 12-input requirement before considering alternative PLD families.

Part Context

This component is part of the TIBPAL16 series, an evolution of the classic PAL16R8 architecture. It utilizes Texas Instruments' Impact-X technology to improve speed and reliability over earlier generations while maintaining pin compatibility with standard PAL devices.

Replacement Considerations

Direct pin-compatible replacements include other TIBPAL16R8 speed grades such as TIBPAL16R8-15CN or TIBPAL16R8-20CN. Verify that the substitute's propagation delay meets the timing requirements of the specific application circuit.
