54C905J

Overview

The 54C905J is a high-speed CMOS logic gate manufactured by Rochester Electronics. It features a 16-bit wide AND-OR-Invert (AOI) architecture, providing complex combinational logic functionality in a single package. The device supports operation within the standard military temperature range of -55°C to 125°C, ensuring reliability in harsh environments. It utilizes advanced CHMOS III technology for low power consumption and high noise immunity. The component is housed in a ceramic dual-in-line package with 24 terminals, designed for direct surface or through-hole integration into industrial control systems.

Feature Summary

• Implements 16-bit wide AND-OR-Invert Boolean logic functions
• Operates reliably across the full military temperature spectrum
• Utilizes CHMOS III technology for enhanced performance

Applications

• Military-grade embedded control systems
• Industrial automation logic processing
• Aerospace avionics data routing

Procurement Notes

Verify that the specific lot corresponds to the original OEM specifications, as Rochester Electronics guarantees performance to these standards. Confirm the package material is ceramic, suitable for the required thermal and mechanical stress conditions. Ensure the date code aligns with your supply chain requirements, noting that components are sourced from authorized manufacturing channels.

Selection Notes

Select this component when a single gate solution for complex 16-input logic is required in a military-rated environment. It is appropriate for designs prioritizing low power consumption alongside high-speed switching capabilities. Consider the 24-pin DIP form factor for legacy board layouts requiring robust physical connectivity and thermal dissipation characteristics typical of ceramic packages.

Part Context

This part belongs to the 54C series of high-speed CMOS logic devices. It is functionally related to other AOI gates like the 54L54 but offers superior speed and lower power characteristics due to its CMOS construction. The 54C905J serves as a critical building block for complex digital signal processing paths in defense and aerospace applications where component longevity and environmental resilience are mandatory.

Replacement Considerations

Direct substitutes include the SN54C905J from Texas Instruments. Verify pin compatibility and electrical parameters against the original design specifications before substitution.
