TIBPAL16R6-20MJB

Overview

The TIBPAL16R6-20MJB is a high-performance Impact PAL circuit manufactured by Texas Instruments, designed for military temperature ranges (-55°C to 125°C). It features an architecture with 8 dedicated inputs, 2 I/O ports, and 6 registered outputs. The device utilizes Advanced Low-Power Schottky technology with titanium-tungsten fuses. Key electrical parameters include a maximum propagation delay of 20 ns, a maximum clock frequency of 41.6 MHz, and a supply voltage range of 4.5 V to 5.5 V. It operates within a standard 5 V logic family.

Feature Summary

• Military-grade operation characterized from -55°C to 125°C
• Registered output architecture with power-up clear feature
• High-speed performance with 20 ns max propagation delay
• Compatible with standard TTL logic levels

Applications

• Military aerospace systems requiring wide temperature tolerance
• Industrial control logic replacement for legacy PAL devices
• State machine implementation in harsh environments

Procurement Notes

Verify the specific ordering suffix 'JB' corresponds to the Ceramic Dual In-line Package (CDIP) with 20 pins. Confirm RoHS compliance status as the datasheet indicates 'No SNPB' for this package type. Check current production status, as related R6 variants are marked NRND (Not Recommended for New Designs). Ensure programming equipment supports titanium-tungsten fuse technology.

Selection Notes

Select this component when military temperature stability (-55°C to 125°C) is required alongside registered output functionality. Compare against the C-suffix variants if only commercial temperatures (0°C to 75°C) are needed. Verify that the 6 registered outputs and 2 I/O ports meet the design's pin count requirements. Consider the 41.6 MHz maximum clock frequency limit for timing constraints.

Part Context

This part belongs to the TIBPAL16 series of High-Performance Impact PAL circuits. It is functionally equivalent but faster than older PAL16R6A devices. The 'M' suffix denotes the military temperature range, while 'JB' specifies the ceramic DIP package. It serves as a drop-in replacement for legacy programmable logic in existing military or industrial hardware designs.

Replacement Considerations

Public confirmed substitute part numbers include TIBPAL16R6-20MJB.A and 5962-8515503RA. Note that the TIBPAL16R6-20MJB variant is listed as NRND (Not Recommended for New Designs) in the packaging addendum.
