Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the obsolete status and lifecycle stage before procurement, as this component may no longer be in production by Fairchild Semiconductor. Confirm package integrity and pin compatibility with existing designs. Check for RoHS compliance information if required by specific manufacturing standards. Ensure sourcing from authorized distributors to guarantee authenticity and traceability of the semiconductor unit.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an inverting octal buffer with three-state capability is required for bus systems. Consider the 2 V to 6 V operating range and 24 mA drive strength for load requirements. Evaluate the 10 ns propagation delay at 3.3 V against system timing constraints. Verify that the 20-DIP package fits the available PCB footprint and assembly processes.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACQ series of logic ICs, specifically functioning as an octal buffer/line driver. It shares functional similarities with the 74AC240 and 74ACT240 families but includes specific Q-series characteristics. The device is categorized under buffers, drivers, and receivers within the broader logic IC product line offered by Fairchild and ON Semiconductor.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include MM74HC240N and 74AC240PC. Verify electrical compatibility and pinout alignment before substitution due to potential differences in input/output characteristics between HC and AC families.
