TIBPAL20R6-10CFN

Overview

The TIBPAL20R6-10CFN is a High-Performance IMPACT-X PAL circuit manufactured by Texas Instruments. It features 12 inputs and 8 outputs, with 6 registered Q outputs and 2 I/O ports. The device utilizes Advanced Low-Power Schottky technology and titanium-tungsten fuses for reliable operation. Key electrical parameters include a maximum propagation delay of 10 ns, a nominal supply voltage of 5 V, and an operating temperature range of 0°C to 75°C. It supports a maximum clock frequency of 71.4 MHz without feedback and includes power-up clear functionality for registered devices.

Feature Summary

• High-speed performance with 10 ns max propagation delay and 71.4 MHz max clock frequency
• Registered output architecture with preload capability for simplified testing
• Power-up clear feature sets all registers to low level upon initialization
• Security fuse prevents unauthorized duplication of the logic design

Applications

• State-machine designs requiring external feedback paths
• Counter configurations utilizing internal feedback loops
• Custom function implementation replacing conventional TTL logic
• Systems requiring asynchronous register preloading during test sequences

Procurement Notes

Verify that the ordering suffix 'CFN' corresponds to the Plastic Chip Carrier package variant as specified in the datasheet. Confirm compliance requirements, noting that the C-series is characterized for commercial temperatures (0°C to 75°C). Ensure programming equipment supports the specific titanium-tungsten fuse technology used in this IMPACT-X family.

Selection Notes

Select the TIBPAL20R6-10CFN when six registered outputs and two bidirectional I/O ports are required within a 24-pin footprint. Choose this model over the TIBPAL20L8 or TIBPAL20R4 variants if registered output timing and preload features are necessary. Verify that the plastic chip carrier package fits the board space constraints compared to DIP options.

Part Context

This component belongs to the TIBPAL20xx-10C series, which includes the TIBPAL20L8-10C, TIBPAL20R4-10C, and TIBPAL20R8-10C. All devices in this series share the same high-performance IMPACT-X architecture and 10 ns speed grade but differ in output configuration and registered port counts.

Replacement Considerations

Functionally equivalent parts within the same series include TIBPAL20R4-10C and TIBPAL20R8-10C. Substitution requires verifying pin compatibility and ensuring the target device provides sufficient registered outputs or I/O ports for the specific application logic.
