Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component status as discontinued or obsolete before procurement planning. Confirm that the 20-Pin Plastic DIP package (SOT146-1) matches the target footprint. Ensure the operating temperature range meets system requirements. Check RoHS compliance documentation for regulatory adherence. Validate that the specific ordering suffix aligns with the required packaging format.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with 3-state control is required. The device provides ideal interface capabilities for increasing fan-out of MOS microprocessors. Consider the functional similarity to the 74F240 if non-inverting buffers are needed instead. Evaluate the low power consumption characteristics for light bus loading applications.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74F series of integrated circuits, known for fast switching speeds. It is functionally similar to the 74F240 and 74F241 models. The manufacturer originally released this specification under Philips Semiconductors before transitioning to NXP USA Inc. The device utilizes a standard 20-pin dual in-line package configuration.
