TIBPAL16L8-7CN

Overview

The TIBPAL16L8-7CN is a high-performance IMPACT-X PAL circuit featuring 10 inputs, 2 dedicated outputs, and 6 I/O lines. It operates within a 0°C to 75°C temperature range with a maximum propagation delay of 7 ns. The device supports a minimum frequency of 100 MHz without feedback and utilizes Advanced Low-Power Schottky technology for reliable TTL logic substitution.

Feature Summary

• Combines Advanced Low-Power Schottky technology with titanium-tungsten fuses for high-speed operation.
• Includes preload capability on output registers to simplify testing sequences.
• Features power-up clear functionality where all register outputs initialize to a low level.
• Incorporates a security fuse mechanism to prevent unauthorized duplication.

Applications

• High-speed counter designs utilizing internal feedback configurations.
• State-machine implementations requiring external feedback loops.
• Custom function logic design replacing conventional discrete TTL gates.
• System initialization circuits leveraging automatic power-up reset states.

Procurement Notes

Verify the specific package suffix (N for plastic DIP or J for ceramic DIP) against the required mechanical footprint. Confirm that the 0°C to 75°C commercial temperature rating aligns with the operational environment. Check current availability status as this series may be classified as obsolete by the manufacturer.

Selection Notes

Select this component when functional equivalence to standard PAL16L8 devices is required but higher speed performance is necessary. Ensure the design accommodates the 5V supply voltage and considers the specific input/output configuration of ten inputs and eight total output ports.

Part Context

This device belongs to the Texas Instruments IMPACT-X PAL family, designed as faster substitutes for existing 20-pin programmable logic devices. The 'C' suffix denotes the commercial temperature grade, while the 'N' indicates a plastic dual in-line package. It shares architectural similarities with registered variants like the TIBPAL16R4.

Replacement Considerations

Direct replacements include other TIBPAL16L8 variants with different speed grades or package types, such as the TIBPAL16L8-10M. Designers should verify that any substitute maintains the same pinout and logical structure while meeting the specific timing requirements of the application.
