TIBPAL20R8-7CNT

Overview

The TIBPAL20R8-7CNT is a high-performance PAL circuit from Texas Instruments, utilizing IMPACT-X technology with titanium-tungsten fuses. It features 12 inputs and 8 registered outputs with 3-state buffers. The device operates at a maximum frequency of 100 MHz without feedback and achieves a propagation delay of up to 7 ns. It supports preload capability for output registers and includes power-up clear functionality. The component is housed in a 24-pin PDIP package and is characterized for operation within the commercial temperature range of 0°C to 75°C.

Feature Summary

• High-speed performance with 100 MHz maximum frequency and 7 ns propagation delay
• Registered I/O architecture with 8 outputs featuring 3-state buffers
• Preload capability on output registers simplifies testing procedures
• Power-up clear sets all register outputs to low level upon initialization

Applications

• Complex state machine implementations requiring registered outputs
• High-speed digital logic replacement for conventional TTL circuits
• Counter designs utilizing internal feedback configurations
• Custom function design requiring compact board space reduction

Procurement Notes

Verify the specific suffix 'CNT' corresponds to the 24-pin PDIP NT package configuration. Confirm that the '7C' speed grade aligns with the required 100 MHz operational frequency and 0°C to 75°C temperature range. Ensure programming equipment supports the titanium-tungsten fuse technology specified for this IMPACT-X series device.

Selection Notes

Select the TIBPAL20R8-7CNT when eight registered outputs with 3-state control are necessary. This model provides higher speed (100 MHz) compared to the -10M series (62.5 MHz). Choose this part over unregistered variants like the TIBPAL20L8 if synchronous logic behavior and preload capabilities are required for system initialization.

Part Context

This component belongs to the TIBPAL20 family of programmable array logic devices. It serves as a functional equivalent but faster alternative to existing 24-pin PLD circuits. The IMPACT-X technology combines Advanced Low-Power Schottky processes with titanium-tungsten fuses to ensure reliable high-performance operation suitable for demanding digital applications.
