TIBPAL16R4-12CN

Overview

The TIBPAL16R4-12CN is a high-performance Impact-X PAL programmable logic device manufactured by Texas Instruments. It features a 256-product-term macrocell architecture with 16 inputs and 8 registered outputs, housed in a 20-pin PDIP package. The component operates at a maximum propagation delay of 12 ns and supports a system clock frequency up to 83 MHz. Designed for 5V operation, it provides robust digital logic implementation capabilities within the TIBPAL16 family.

Feature Summary

• Impact-X PAL architecture with 256 product terms
• 16 dedicated inputs and 8 registered outputs
• 12 ns maximum propagation delay
• 20-pin Plastic Dual In-Line Package (PDIP)

Applications

• Digital state machine implementation
• Address decoding logic
• Bus protocol interfacing

Part Context

This component belongs to the TIBPAL16 series of Simple Programmable Logic Devices (SPLDs). It shares architectural similarities with other members like the TIBPAL16R4-25CN but offers faster switching speeds. The 'R4' suffix indicates the registered output configuration, while '12' denotes the speed grade.

Replacement Considerations

Direct replacements include other TIBPAL16R4 variants with compatible speed grades, such as the TIBPAL16R4-25CN or TIBPAL16R4-15CN. Verify pin compatibility and timing requirements when substituting.
