SN74F543DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F543DWR is an octal registered bus transceiver from the Texas Instruments SN74F series, designed for high-speed digital applications. It features eight non-inverting channels with three-state outputs and TTL-compatible input and output levels. The device operates within a supply voltage range of 4.5 V to 5.5 V and exhibits a propagation delay of 7.5 ns. It provides a low-level output current of 64 mA and a high-level output current of -15 mA. Manufactured in a 24-pin SOIC package, it supports surface-mount installation and functions reliably across an operating temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-24 package and 'R' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the component meets the required industrial temperature specifications for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring fast switching speeds within standard 5V logic environments. The SN74F series offers superior performance compared to standard 74LS counterparts. Consider the 64 mA drive capability for heavy capacitive loads. Verify that the 0°C to +70°C operating range aligns with system thermal constraints.
