SNJ54LVTH374W

Flip Flops Overview

The SNJ54LVTH374W is an octal edge-triggered D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and supports a maximum clock frequency of 150 MHz. The device provides high drive capability with output currents of -32 mA (high) and 64 mA (low). It is housed in a 20-lead ceramic flatpack (CFP) package and is qualified for extended industrial temperature ranges from -55°C to +125°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops with positive-edge triggering.
• Three-state outputs enable direct connection to bus lines without additional interface logic.
• High-speed operation supporting data transfer rates up to 150 MHz.
• Robust output drive strength suitable for driving high capacitive or low-impedance loads.

Flip Flops Applications

• Parallel-to-serial data conversion in communication systems.
• Register buffering for high-speed microprocessor interfaces.
• Clock distribution networks requiring precise timing control.
• Data acquisition systems operating in extreme environmental conditions.

Flip Flops Procurement Notes

Verify the specific ordering suffix 'W' to confirm the ceramic flatpack package type and military-grade temperature rating. Ensure compatibility with existing board layouts for 20-lead CFP footprints. Confirm that the 2.7 V to 3.6 V supply voltage aligns with system power rails. Validate that the -55°C to +125°C operating range meets application thermal requirements.

Flip Flops Selection Notes

Select this component when high-speed octal latching with three-state outputs is required in harsh environments. It is suitable for applications demanding robust drive strength and wide temperature tolerance. Consider alternative packages if surface-mount technology is preferred over through-hole ceramic packaging. Verify input compatibility with TTL logic levels if interfacing with legacy systems.

Flip Flops Part Context

This part belongs to the LVTH series of low-voltage CMOS logic devices. It complements other octal flip-flops like the SN74LVTH374 but offers extended temperature performance and a durable ceramic package. The family focuses on high-speed data handling with reduced power consumption compared to older standard voltage logic families.

Flip Flops Replacement Considerations

SNJ54LVTH374DW: Same functional specifications in a SOIC package. SNJ54LVTH374PW: Same functional specifications in a TSSOP package. SNJ54ABT374W: Similar octal flip-flop with three-state outputs but different speed and drive characteristics.
