SN74F623DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F623DWR is an octal bus transceiver from the Texas Instruments SN74F series, housed in a 20-pin SOIC package. It features non-inverting logic with three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device supports TTL input and output levels, providing a low-level output current of 64 mA and a high-level output current of -15 mA. It functions as a single-element, eight-bit transceiver suitable for surface-mount applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the SN74F series designation matches the required speed and power specifications for the target design. Ensure the SOIC-20 footprint aligns with the PCB layout. Cross-reference the manufacturer part number against official Texas Instruments documentation to confirm current production status and compliance details.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring bidirectional data transfer between buses with high drive capability. The F series offers faster switching speeds compared to standard LS logic. Consider the 64 mA low-level sink current for heavy capacitive loads. Verify that the 4.5 V to 5.5 V operating range fits the system power supply constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74F family of high-speed CMOS logic devices. It serves as a bidirectional data translator, allowing data flow control between two buses. The octal configuration provides eight independent channels in a single package, reducing board space compared to individual bit transceivers.
