Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer designation as Fairchild Semiconductor has been integrated into ON Semiconductor. Confirm the exact suffix matches the required package type and tape-and-reel specifications. Check current availability status as older manufacturing runs may be discontinued or replaced by updated part numbers from the successor entity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with three-state control is required for bus applications. Ensure the operating voltage aligns with the 2V to 6V specification. Consider the TSSOP package dimensions for PCB layout constraints. Verify that the 24mA drive current meets the load requirements of the connected circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74AC logic family, known for high-speed CMOS operation. It is functionally compatible with the standard 74LS240 series but offers faster switching speeds and lower power consumption. The octal configuration allows for efficient handling of wide data buses or multiple control signals within a single integrated circuit package.
