Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix WD corresponds to the ceramic flat package (CFP) variant. Confirm that the MIL-PRF-38535 compliance status matches project requirements, as production processing may not include testing of all parameters unless explicitly noted. Ensure compatibility with the required operating temperature range and supply voltage specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when military-grade temperature operation from -55°C to 125°C is required. The CFP package is suitable for applications needing hermetic sealing or specific thermal management characteristics associated with ceramic packages. Consider the flow-through architecture for dense PCB layouts requiring optimized signal routing paths.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments Widebus family, which includes various 16-bit logic devices. The SN54 series designation indicates military-grade qualification, distinguishing it from the commercial SN74 series counterparts like the SN74ABT16244A. The WD suffix specifically identifies the 48-lead ceramic dual flatpack package option.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device ensure high-impedance state during power-up or power-down?

To ensure the high-impedance state during power-up or power-down, the OE (Output Enable) pin should be tied to VCC through a pullup resistor.

What is the latch-up performance specification?

The latch-up performance exceeds 500 mA per JESD 70 standard.
