TIBPAL16R8-10MWB

Overview

The TIBPAL16R8-10MWB is a High-Performance IMPACT-X PAL circuit manufactured by Texas Instruments. It features 8 dedicated inputs, 8 registered outputs with 3-state buffers, and an I/O port. The device utilizes Advanced Low-Power Schottky technology with titanium-tungsten fuses for reliable high-speed operation. It operates within a full military temperature range of -55°C to 125°C and supports a maximum clock frequency of 62.5 MHz. Key electrical characteristics include a maximum propagation delay of 10 ns for combinational paths and 9 ns for registered outputs. The supply voltage ranges from 4.5 V to 5.5 V, with a typical operating current of 200 mA at 5.5 V.

Feature Summary

• High-performance IMPACT-X architecture with 62.5 MHz minimum clock frequency
• Registered outputs with preload capability for simplified testing
• Power-up clear feature sets all registers to low level upon initialization
• Security fuse prevents logic duplication

Applications

• Counter designs using internal feedback configurations
• State-machine implementations requiring external feedback
• Custom function design replacing conventional TTL logic

Procurement Notes

This component is marked as obsolete and no longer available from Texas Instruments. Verification of availability should focus on secondary market distributors or surplus suppliers. Ensure the specific WB suffix corresponds to the ceramic chip carrier package variant when sourcing replacements.

Selection Notes

Select this part for applications requiring registered outputs with 3-state buffering in a military temperature environment. Compare against the TIBPAL16R8-7C series if higher speed (100 MHz) is needed but commercial temperature range suffices. Verify that the 10 ns propagation delay meets system timing requirements for both combinational and registered paths.

Part Context

The TIBPAL16R8-10MWB belongs to the TIBPAL16R' series of programmable array logic devices. It is functionally equivalent to other 20-pin PLDs but offers faster performance through IMPACT-X technology. The '10M' designation indicates the 10 ns speed grade and military temperature rating, while 'WB' specifies the ceramic chip carrier package.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. As the device is obsolete, consider evaluating the TIBPAL16R8-7C series for functional compatibility, noting differences in speed grade and operating temperature range.
