TIBPAL16L8-30MJB

Overview

The TIBPAL16L8-30MJB is a low-power high-performance IMPACT PAL circuit featuring 10 dedicated inputs, 6 I/O ports, and 4 registered outputs. It utilizes titanium-tungsten fuses for programmability. The M suffix indicates characterization for the full military temperature range of -55°C to 125°C. Maximum propagation delay is 30 ns with a maximum clock frequency of 25 MHz. Supply voltage ranges from 4.5 V to 5.5 V.

Feature Summary

• Combines Advanced Low-Power Schottky technology with titanium-tungsten fuses for reliable high-performance logic.
• Functionally equivalent but faster than standard PAL16L8A devices.
• Registered outputs feature power-up clear, setting all registers high upon initialization.

Applications

• Military-grade state machine implementation
• High-speed decoding logic in harsh environments
• Replacement for legacy TTL logic in aerospace systems

Procurement Notes

Verify that the ordering suffix JB corresponds to the ceramic DIP package suitable for military specifications. Confirm the device meets the required MIL-STD reliability standards if applicable. Ensure programming equipment supports titanium-tungsten fuse architectures. Check for RoHS exemption status as these are specialized military components.

Selection Notes

Select this part when military temperature operation (-55°C to 125°C) is mandatory. Choose the M suffix over C suffix for extended thermal performance. Verify that the 30 ns speed meets system timing requirements compared to faster 25 ns variants. Ensure the 10-input/6-I/O/4-register configuration matches the design logic density needs.

Part Context

This component belongs to the Texas Instruments IMPACT PAL family, designed as high-performance substitutes for conventional TTL logic. It offers compact board space reduction through chip carriers or DIP packages. The series provides easy programmability for custom function design using widely available software and programmers.

Replacement Considerations

Publicly confirmed substitutes include other TIBPAL16L8 variants with different speed grades (e.g., 25C) or package options (CFP, LCCC). Standard PAL16L8A devices are functionally equivalent but slower. Verify pinout compatibility and electrical characteristics before substitution.
