SNJ54LVT16373WD

Overview

The SNJ54LVT16373WD is a military-grade, 16-bit transparent D-type latch manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 2.0 V to 3.6 V. The device utilizes a ceramic flatpack (CFP) package with 48 pins, designed for surface mount installation. It supports an extended industrial temperature range from -55°C to +125°C. Key electrical characteristics include a propagation delay of 5.4 ns at 3.3 V, low static current consumption, and robust output drive capabilities suitable for high-speed digital applications in demanding environments.

Feature Summary

• Military-grade reliability with extended temperature operation
• Three-state outputs for bus-oriented memory management
• Transparent latch architecture for direct data path control
• Low power consumption compatible with 3.3 V systems

Applications

• Military aerospace communication systems
• High-reliability industrial data acquisition
• Automotive electronics requiring wide temperature tolerance
• Bus-oriented memory register architectures

Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and temperature grade are selected. Confirm that the procurement channel provides traceability documentation required for military or aerospace specifications. Check for availability constraints as this component may be subject to limited production runs or special order requirements. Ensure compatibility with existing board layouts regarding the ceramic flatpack footprint.

Selection Notes

Select this component when military-grade performance and wide temperature operation are mandatory. Compare against commercial variants if environmental conditions do not require -55°C to +125°C range. Consider the CFP-48 package size relative to available PCB space. Verify that the 3.3 V logic levels align with the system's I/O standards. Evaluate the trade-off between the higher cost of military-grade parts and the necessity for long-term reliability in harsh environments.

Part Context

This part belongs to the LVT (Low Voltage TTL) family of logic devices, specifically designed for 3.3 V applications. It is the military-grade counterpart to the commercial SN54LVT16373 series. The device functions as a high-performance 16-bit storage element, providing a solution for parallel data latching in complex digital circuits where signal integrity and speed are critical.

Replacement Considerations

Direct replacements include other military-grade 16-bit latches from the same manufacturer family. Verify pinout compatibility before substituting with commercial grade parts, as temperature ranges differ significantly. Cross-reference with equivalent offerings from other manufacturers ensuring matching voltage and package specifications.
