SNJ54CBTD3384FK

Signal Switches, Multiplexers, Decoders Overview

The SNJ54CBTD3384FK is a military-grade digital bus switch IC providing ten bits of high-speed TTL-compatible switching. It features an on-state resistance of 5 ohms and a propagation delay of 0.25 ns. The device operates with a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to 125°C. Packaged in a 28-pin LCCC (FK) configuration, it includes integrated level-shifting capabilities via a diode to VCC.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides ten bits of high-speed bus switching organized as two independent 5-bit switches
• Features low on-state resistance to prevent added propagation delay during signal transmission
• Includes integrated level-shifting capability for transitioning between 5-V and 3.3-V signal levels
• Maintains TTL-compatible input levels for direct interface with standard logic families

Signal Switches, Multiplexers, Decoders Applications

• Military and defense applications requiring QML certification
• High-speed data bus routing in aerospace systems
• Level-shifting interfaces between 5-V and 3.3-V logic domains
• Critical electronic systems demanding extended temperature operation

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix FK to confirm the 28-pin LCCC package type. Ensure the part number prefix SNJ indicates the military-grade variant suitable for harsh environments. Confirm RoHS exemption status if required by assembly specifications. Validate that the active production status aligns with long-term availability needs for defense contracts.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when military-grade reliability and wide temperature tolerance are mandatory. The LCCC package offers robust mechanical stability for ruggedized designs. Consider the 5-ohm on-resistance for low-loss signal paths. Verify compatibility with existing TTL control signals before integration into the system architecture.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the SN54CBTD3384 family, which provides high-performance bus switching solutions. The SNJ prefix designates the military version, distinct from the commercial SN74 counterpart. It serves as a critical interconnect element in complex digital systems where signal integrity and environmental resilience are paramount.
