Comparators Procurement Notes

Verify the manufacturer designation as National Semiconductor, now part of Microchip Technology. Confirm the specific suffix S2A-RH corresponds to the 20-CLCC package and bulk packaging format. Ensure the component meets the required military temperature specifications (-55°C to 125°C) for your application environment before procurement.

Comparators Selection Notes

Select this component when an 8-bit identity comparator with active low outputs is required for harsh environments. Consider the 2V to 6V supply range and 80 µA quiescent current for power budgeting. The 20-CLCC surface-mount package dictates the PCB layout requirements. Verify compatibility with existing logic families if interfacing with other components.

Comparators Part Context

This part belongs to the 54AC series of logic comparators, which are characterized by their robust construction and wide operating temperature ranges suitable for military and aerospace standards. The JM prefix typically indicates a military-grade variant, ensuring higher reliability compared to commercial counterparts.

Comparators Replacement Considerations

Check for direct equivalents from Microchip or authorized distributors that maintain the 54AC series specifications. Ensure any substitute matches the 20-CLCC package and active low output configuration. Verify that the replacement supports the same voltage and temperature ranges.
