SN74HC240NSRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC240NSRE4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HC logic series. It features eight unidirectional channels with three-state outputs controlled by a low-active enable signal. The device operates within a supply voltage range of 2 V to 6 V and supports a load capacitance of 50 pF. It is housed in a 20-pin Small Outline (SO) package with a maximum length of 12.6 mm. The component functions as a bus driver with a maximum output current of 6 mA and operates reliably across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RE4 indicates lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your system's environmental specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is required for high-speed CMOS logic applications. It is suitable for designs needing wide supply voltage flexibility between 2 V and 6 V. Consider the 20-pin SO package for surface-mount assembly constraints. Verify that the unidirectional nature meets the data flow requirements of your specific circuit design.
