SNJ54CBT3383JT

Signal Switches, Multiplexers, Decoders Overview

The SNJ54CBT3383JT is a military-grade, 10-bit FET bus-exchange switch manufactured by Texas Instruments. It provides high-speed TTL-compatible bus switching or exchanging capabilities with low and flat ON-state resistance (rON). The device operates within an extended temperature range of -55°C to +125°C and utilizes a ceramic dual in-line package (CDIP) with 20 pins. Designed for robust performance in demanding environments, it supports bidirectional data flow control across ten independent channels.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides ten bits of high-speed TTL-compatible bus switching or exchanging functionality
• Features low and flat ON-state resistance (rON) for consistent signal integrity
• Constructed with ceramic packaging suitable for military and high-reliability applications

Signal Switches, Multiplexers, Decoders Applications

• Military avionics systems requiring high-reliability signal routing
• Harsh environment industrial control buses
• High-speed data exchange interfaces in defense electronics

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'JT' indicates the military grade qualification and ceramic DIP package when sourcing. Confirm that the component meets the required environmental specifications for your application, as commercial equivalents may lack the extended temperature range and ruggedization. Ensure compatibility with existing board layouts designed for the CDIP form factor.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when ten-channel bidirectional switching is required in extreme temperature conditions. It is appropriate for designs needing TTL compatibility and low on-resistance without the complexity of active level shifting. Consider the ceramic package constraints regarding PCB mounting and thermal management compared to plastic alternatives.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SNx4CBT3383 family of 10-bit bus-exchange switches. While commercial variants like the SN74CBT3383 exist, the SNJ prefix denotes JANS/JAN military qualification. The 'JT' suffix specifically identifies the ceramic dual in-line package variant, distinguishing it from other package options within the same logical family.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct replacements include other SNJ54CBT3383 variants with different package suffixes if pinout compatibility is maintained. Cross-reference with SNJ54HC series decoders only if functional requirements shift from bus switching to decoding, noting significant architectural differences.
