SNJ54ACT11241FK

Overview

The SNJ54ACT11241FK is a military-grade, dual 4-bit bus driver from the AC series manufactured by Texas Instruments. It features true outputs and operates within a ceramic DIP-24 package with a 0.300-inch body width. The device supports unidirectional data transfer with specific enable control logic. Key electrical parameters include a maximum output current of 24 mA and a load capacitance rating of 50 pF. It is designed for high-reliability applications requiring robust signal integrity in harsh environments.

Feature Summary

• Dual independent 4-bit bus driver architecture providing eight total channels
• True output polarity for non-inverting signal transmission
• Ceramic dual in-line package (CDIP) construction for enhanced durability
• Military-grade qualification ensuring operation under extreme conditions

Applications

• Military avionics systems requiring radiation-hardened or high-reliability logic
• Spacecraft communication bus interfaces
• Defense electronics signal routing
• High-reliability industrial control systems

Procurement Notes

Verify the RoHS status carefully as this component is explicitly listed as non-compliant in official databases. Confirm the package type is CDIP-24 ceramic rather than plastic variants. Ensure the manufacturer is Texas Instruments to avoid counterfeit military surplus. Check for moisture sensitivity level compliance if storage conditions are critical. Validate the part number suffix FK against your bill of materials to ensure correct pinout and specification alignment.

Selection Notes

Select this component when military-grade reliability and ceramic packaging are mandatory requirements. It serves as a direct functional equivalent to other 54AC/54ACT series drivers but offers superior environmental tolerance compared to commercial grades. Consider the DIP-24 form factor for through-hole mounting constraints. Evaluate the 24 mA drive capability against the load requirements of the destination circuitry to ensure adequate noise margins.

Part Context

This part belongs to the Texas Instruments 54AC/54ACT family of high-speed CMOS logic devices. The 54 prefix denotes military-grade qualification, distinguishing it from the commercial 74 series. The ACT variant indicates Advanced Technology CMOS, offering speed comparable to LS TTL with lower power consumption. This specific model provides dual 4-bit buffering capabilities essential for complex digital system architectures.

Replacement Considerations

SNJ54ACT11241FK is functionally compatible with other 54ACT11241 variants in the same package. Verify pin compatibility before substituting with commercial 74ACT11241 parts, noting the lack of military qualification in commercial equivalents. Cross-reference with SNJ54AC11241 if AC speed specifications are sufficient instead of ACT speeds.
