Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and manufacturer lot details against the official datasheet before procurement. Confirm that the 74ACT240PC designation corresponds to the correct pinout and electrical specifications required by the design. Ensure compliance with RoHS directives if applicable to the target market. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with three-state outputs is required for bus applications. The ACT series offers improved speed and lower power consumption compared to older AC/LS families. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range. Verify that the DIP package format meets the PCB layout requirements for the specific application environment.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74ACT240PC is part of the broader 74ACT240 family of octal buffers. It shares functional similarities with non-inverting variants like the 74ACT244 but provides inverted logic. This component is commonly used in digital systems requiring high-density interconnects and reliable bus isolation. The PC suffix typically denotes a plastic dual in-line package (DIP) form factor.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include MC74ACT240PC and MM74ACT240PC from other manufacturers offering equivalent ACT-series performance. Ensure pin compatibility and electrical parameters match the original design requirements.
