8103609RA

Overview

The PAL16L8AM is a standard high-speed programmable array logic device from Texas Instruments, characterized for military-grade operation across the -55°C to 125°C temperature range. It utilizes Advanced Low-Power Schottky technology with titanium-tungsten fuses. The device features a 32x64 AND-OR array, providing ten inputs and six I/O ports alongside two dedicated outputs. Electrical specifications include a maximum operating frequency of 25 MHz, a typical propagation delay of 30 ns, and a supply voltage range of 4.5 V to 5.5 V.

Feature Summary

• Combines high-speed performance with low power dissipation using Advanced Low-Power Schottky technology.
• Features a flexible 32x64 programmable array architecture suitable for complex custom logic functions.
• Supports multiple package options including ceramic DIP, flat package, and chip carrier formats.

Applications

• Replacement for conventional TTL logic in high-performance digital systems.
• Implementation of custom combinational logic functions on compact circuit boards.
• Military and aerospace electronic systems requiring wide temperature tolerance.
• Design of address decoding and control logic in industrial equipment.

Procurement Notes

Verify that the specific ordering suffix matches the required package type (CDIP, CFP, or LCCC) and speed grade. Confirm the component status as active production or restricted supply through official Texas Instruments channels. Ensure compatibility with existing programming hardware and software tools before procurement.

Selection Notes

Select the PAL16L8AM when a high-speed, non-registered logic solution is required within the military temperature range. Consider the Half-Power variants if lower power consumption is prioritized over maximum switching speeds. Evaluate package availability based on board space constraints and mounting requirements.

Part Context

This component belongs to the PAL16' M series of Standard High-Speed PAL circuits manufactured by Texas Instruments. The 'M' designation indicates qualification for the full military temperature range. The device serves as a direct functional substitute for similar legacy PAL devices in established designs.

Replacement Considerations

PAL16L8A-2M offers identical functionality with reduced switching speeds and power consumption. Other members of the PAL16 family, such as PAL16R4AM or PAL16R8AM, provide registered outputs but differ in pin configuration and I/O port counts.
