TIBPAL16R6-15MWB

Overview

The TIBPAL16R6-15MWB is a high-performance Impact PAL circuit manufactured by Texas Instruments, designed for military temperature operation ranging from -55°C to 125°C. It utilizes Advanced Low-Power Schottky technology with titanium-tungsten fuses. The device features 8 dedicated inputs and 2 I/O ports, providing 6 registered outputs (Q) and 2 I/O lines. Key electrical parameters include a maximum propagation delay of 15 ns for combinational paths and 12 ns for registered paths, with a maximum clock frequency of 50 MHz. Power consumption is typically 220 mA at VCC = 5.5 V.

Feature Summary

• Military-grade reliability with operation over the full temperature range of -55°C to 125°C
• High-speed performance with 15 ns max propagation delay and 50 MHz clock capability
• Configurable I/O structure offering 6 registered outputs and 2 I/O ports
• Power-up clear function ensures all register outputs initialize to a known state

Applications

• Military avionics systems requiring robust programmable logic
• Spacecraft control circuits operating in extreme thermal environments
• Defense communication equipment interface logic
• Harsh environment industrial control applications

Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the Ceramic Flat Package (CFP) when sourcing. Confirm that the component meets the required MIL-STD specifications if applicable to the design. Check the current production status, as legacy PLD families may have limited availability or last-time-buy constraints. Ensure programming equipment supports the specific algorithm for the TIBPAL16R6-15M series.

Selection Notes

Select this part when a combination of registered outputs and I/O flexibility is needed within a 20-pin ceramic package. Compare against TIBPAL16R4-15MWB for fewer outputs or TIBPAL16R8-15MWB for more registered outputs but no I/O. Ensure the design accounts for the 15 ns max propagation delay and 50 MHz max clock frequency limits under military temperature conditions.

Part Context

This component belongs to the TIBPAL16 family of High-Performance Impact PAL circuits. It shares the same pinout and architectural foundation as the TIBPAL16L8, TIBPAL16R4, and TIBPAL16R8 variants. The 'R6' designation specifically indicates the configuration of 6 registered outputs and 2 I/O ports, distinguishing it from other members of the series.

Replacement Considerations

Direct replacements must match the 20-pin CFP package and military temperature range. Verify compatibility with existing programming algorithms, as date code variations may require different programming settings.
