TIBPALR19R4CFN

Overview

The TIBPALR19R4CFN is a high-performance Programmable Logic Device (PLD) from Texas Instruments, belonging to the PAL-type family. It features a 25 ns propagation delay and supports TTL logic levels. The device is housed in a 20-pin CFP package and operates within an extended temperature range of -55°C to 125°C. This component provides flexible logic implementation for complex digital designs requiring reliable performance under harsh environmental conditions.

Feature Summary

• Supports high-speed logic operations with a 25 ns propagation delay
• Compatible with standard TTL logic input and output levels
• Designed for operation across an extended industrial temperature range

Applications

• Complex digital logic replacement in industrial control systems
• State machine implementation in aerospace and defense electronics
• Interface logic adaptation in high-reliability computing hardware

Procurement Notes

Verify the specific suffix 'CFN' confirms the ceramic flat pack package and commercial/industrial grade variant. Ensure the part number matches the exact speed grade of 25 ns. Confirm RoHS compliance status if required by assembly specifications. Cross-reference the manufacturer datasheet for pinout compatibility before integration.

Selection Notes

Select this component when designing systems requiring robust PLD functionality with defined timing constraints. The 25 ns delay suits moderate-speed applications where reliability is critical. Consider the 20-pin footprint for board layout. Evaluate thermal management needs given the wide operating temperature range and potential power dissipation in dense logic configurations.

Part Context

This device is part of Texas Instruments' impact PAL series, known for high-speed performance and radiation hardness characteristics suitable for demanding environments. It serves as a direct replacement for older discrete logic solutions, offering reduced board space and improved signal integrity in mission-critical digital circuits.

Replacement Considerations

Direct substitutes include the TIBPALT19R4CNT variant, which shares similar functional characteristics but may differ in package or specific testing criteria. Verify electrical parameters and pin compatibility before substitution to ensure circuit continuity.
