8103607RA

Overview

The PAL16L8AM is a standard high-speed programmable array logic device from Texas Instruments, utilizing Advanced Low-Power Schottky technology. It features a 32x64 AND-OR array with ten inputs and six I/O ports configured as outputs. The 'M' suffix indicates military qualification for operation between -55°C and 125°C. Electrical characteristics include a maximum propagation delay of 30 ns and a clock frequency up to 25 MHz.

Feature Summary

• Combines high-speed performance with low power dissipation using Advanced Low-Power Schottky technology.
• Features titanium-tungsten fuses for reliable programmability and compact circuit board design.
• Military-grade devices characterized for full industrial temperature ranges.

Applications

• Replacing conventional TTL logic in complex digital systems.
• Implementing custom combinational logic functions.
• Designing address decoding circuits.
• Creating control logic for memory interfaces.

Procurement Notes

Verify the specific package variant (CDIP, CFP, or LCCC) required for the application. Confirm that the military temperature rating (-55°C to 125°C) aligns with system environmental specifications. Ensure programming equipment supports the titanium-tungsten fuse architecture defined in the datasheet.

Selection Notes

Select the PAL16L8AM when a fixed-function logic solution requires rapid prototyping or field reprogrammability. Choose this device over registered variants if synchronous storage is not needed. Consider the Half-Power versions if lower power consumption is prioritized over maximum switching speed.

Part Context

This component belongs to the PAL16L8A family of Simple Programmable Logic Devices (SPLD). It serves as a direct hardware replacement for discrete gate arrays, offering higher density and reduced footprint. The device is part of Texas Instruments' legacy PAL portfolio designed for robust digital logic implementation.

Replacement Considerations

PAL16L8A-2M offers half-power characteristics with reduced switching speeds. PAL16R4AM, PAL16R6AM, and PAL16R8AM provide registered output options for sequential logic applications. Catalog versions without the 'M' suffix are available for commercial temperature ranges.
