TIBPAL20L8-5CFN

Overview

The TIBPAL20L8-5CFN is a Simple Programmable Logic Device (SPLD) from Texas Instruments, belonging to the Impact-X PAL family. It features a 24-pin PDIP package and operates within a commercial temperature range of 0°C to +75°C. The device supports a maximum operating frequency of 125 MHz with a typical propagation delay of 5 ns. It requires a supply voltage between 4.75 V and 5 V and draws approximately 210 mA during operation. This component is designed for high-performance logic applications requiring fast switching speeds.

Feature Summary

• Impact-X PAL architecture providing high-speed performance up to 125 MHz
• 5 ns maximum propagation delay for rapid signal processing
• Standard 24-pin Plastic Dual In-line Package (PDIP) for through-hole mounting
• Commercial grade temperature rating spanning 0°C to +75°C

Applications

• High-speed digital logic implementation
• Bus protocol translation circuits
• Address decoding systems
• State machine control logic

Procurement Notes

Verify the specific suffix 'CFN' against official Texas Instruments documentation to confirm exact package dimensions and thermal characteristics. Confirm RoHS compliance status as manufacturing processes evolve. Check current lifecycle status, as older SPLDs may be discontinued or subject to last-time buys. Ensure sourcing channels provide genuine components to avoid counterfeit risks associated with legacy programmable logic devices.

Selection Notes

Select this component when a 5 ns delay and 125 MHz speed are required in a 24-pin DIP format. Compare against the TIBPAL20L8-5CNT variant if lead-free or different packaging options are needed. Ensure the design accommodates the 210 mA power consumption. Verify that the 5V TTL-compatible inputs match the system logic levels. Consider pinout compatibility if replacing existing designs using similar PAL architectures.

Part Context

This part belongs to the Texas Instruments TIBPAL20L8 series of Impact-X PAL devices. These devices offer increased logic capacity compared to standard PALs, featuring 20 input pins and 8 output pins. The series is known for reliability and fast programming yields using Ti-W fuses. It serves as a functional equivalent to certain AMD AMPAL series devices, facilitating migration in legacy designs.

Replacement Considerations

The TIBPAL20L8-5CNT is a documented alternative within the same product family, offering identical electrical specifications. Verify pin-to-pin compatibility before substitution. Other Impact-X PAL variants may require logic reprogramming but fit the same physical footprint.
