TIBPAL16R6-25CN

Overview

The TIBPAL16R6-25CN is a low-power high-performance IMPACT PAL programmable logic device featuring registered outputs. It operates with a maximum propagation delay of 25 ns and supports a clock frequency up to 30 MHz. The device utilizes Advanced Low-Power Schottky technology and titanium-tungsten fuses for reliable performance. It includes power-up clear functionality for all register outputs, ensuring a defined initial state upon system initialization.

Feature Summary

• High-speed operation using Advanced Low-Power Schottky technology
• Registered outputs with automatic power-up clear feature
• Functionally equivalent to legacy PAL16R6A devices

Applications

• State machine implementation requiring synchronous control
• Decoding logic in industrial control systems
• Address decoding for memory subsystems
• General-purpose sequential logic design

Procurement Notes

Verify the specific suffix 'CN' indicates a plastic DIP package with commercial temperature range (0°C to 75°C). Confirm RoHS compliance status as the device may be classified under lifetime-buy or obsolete status depending on current production data. Ensure programming equipment supports titanium-tungsten fuse architecture for successful configuration.

Selection Notes

Select this component when a registered output variant is required instead of the combinational PAL16L8. The '25' suffix denotes a 25 ns speed grade suitable for moderate-frequency applications. Compare against the -30M series if military temperature range (-55°C to 125°C) is necessary for the target environment.

Part Context

This part belongs to the Texas Instruments IMPACT-X PAL family, designed as a drop-in replacement for older standard TTL PAL devices. It combines high performance with low power consumption, making it suitable for upgrading existing designs that utilize conventional PAL16R6A circuits while reducing board space and power requirements.

Replacement Considerations

The TIBPAL16R6-25CN is functionally equivalent to the PAL16R6A. Designers replacing legacy parts should verify that the new device's power-up clear behavior aligns with the original system reset requirements.
