SNJ54ABT125W

Buffers, Drivers, Receivers, Transceivers Overview

The SNJ54ABT125W is a quadruple bus buffer gate with 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from -55°C to 125°C. The device features high-drive outputs capable of sourcing -32 mA and sinking 64 mA. Propagation delays are specified at 4.6 ns maximum at 5 V with a 50 pF load. It includes Ioff and power-up 3-state support for hot-insertion applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features independent line drivers with 3-state outputs that disable when the associated output-enable input is high.
• Supports hot-insertion applications through Ioff circuitry that prevents damaging current backflow during power-down.
• Includes power-up 3-state circuitry to place outputs in a high-impedance state during power transitions.

Buffers, Drivers, Receivers, Transceivers Applications

• Hot-insertion systems requiring controlled signal buffering
• Bus-oriented memory and driver applications
• High-drive digital signal transmission

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific military-grade qualification status and package marking requirements against the latest TI documentation before procurement. Confirm that the CFP (W) package dimensions and thermal characteristics align with the target PCB layout constraints. Ensure compatibility with MIL-PRF-38535 standards if applicable to the design specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring wide industrial or military temperature ranges and robust latch-up protection exceeding 500 mA per JEDEC standards. Consider the CFP package for hermetic sealing needs. Verify that the 4.5 V to 5.5 V supply voltage range matches the system power architecture.
