Procurement Notes

Verify the manufacturer designation as National Semiconductor, noting its acquisition history. Confirm the specific suffix ERQMLV corresponds to the required radiation-hardened or qualified variant if applicable. Ensure the 20-LCCC package dimensions match the design constraints. Request official documentation to validate the operational voltage range and temperature specifications before integration.

Selection Notes

Select this component when a non-inverting transceiver with three-state outputs is required for 5V logic systems. The 20-LCCC ceramic package indicates suitability for harsh environments where standard plastic packages may fail. Consider the bidirectional nature of the bus interface and the need for independent control signals. Verify compatibility with existing FPGA or microcontroller interfaces regarding timing requirements.

Part Context

This part belongs to the ACT series of advanced CMOS logic devices, known for high speed and low power consumption. The QMLV suffix typically denotes qualification for military or space-grade applications, implying stricter manufacturing controls. It serves as a critical interface component between different logic domains or memory banks in complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Users must consult official National Semiconductor or Texas Instruments documentation for verified cross-references. Ensure any replacement matches the 20-LCCC footprint and electrical characteristics precisely.
