54F573FM/B

Overview

The 54F573FM/B is an F/FAST series octal bus driver manufactured by Rochester Electronics. It features true outputs and a ceramic DIP-20 package. Key electrical parameters include a maximum propagation delay of 8 ns, a load capacitance of 50 pF, and a maximum supply current of 50 mA. The device operates within a temperature range of -55 °C to 125 °C.

Feature Summary

• Octal bus driver with true output polarity
• High-speed F/FAST logic series performance
• Hermetic ceramic packaging for harsh environments

Applications

• Military aerospace systems requiring radiation hardness
• Harsh environmental industrial control interfaces
• High-reliability data bus transmission networks

Procurement Notes

Verify the specific revision level and lot traceability against original manufacturer specifications. Confirm that the ceramic hermetic seal integrity meets MIL-STD-883 standards. Ensure the component matches the exact base number and suffix requirements for your system's qualification documentation.

Selection Notes

Select this component when high-speed signal integrity is critical in extreme temperature conditions. The ceramic package provides superior thermal stability compared to plastic alternatives. Verify that the 50 mA supply current fits within your system's power budget constraints.

Part Context

This part belongs to the 54-series military-grade logic family, known for wide temperature operation. Rochester Electronics extends the lifecycle of these components through die-level sourcing and rigorous testing protocols aligned with original datasheets.

Replacement Considerations

Direct substitutes must match the 54F573 base specification and DIP-20 ceramic package. Verify equivalent propagation delay and operating voltage ranges before integration.
