SN74F543DBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F543DBR is an octal registered transceiver from the Texas Instruments SN74F series, designed for 4.5 V to 5.5 V operation. It features eight non-inverting channels with three-state outputs and TTL-compatible input and output levels. The device provides a propagation delay of 7.5 ns, with low-level output current capability of 64 mA and high-level output current of -15 mA. It operates within a temperature range of 0°C to +70°C and is housed in a 24-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the 24-SOIC package and tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the operating temperature range meets system requirements. Cross-reference the manufacturer part number with official datasheets to validate pinout and electrical characteristics before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal registered transceiver with TTL compatibility is required for 5V logic systems. Consider the 7.5 ns propagation delay and 64 mA drive strength for bus applications. Ensure the SOIC-24 package fits the PCB layout constraints and that the 0°C to +70°C commercial temperature range is sufficient for the intended environment.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74F series of fast logic devices manufactured by Texas Instruments. It is functionally similar to other octal transceivers like the SN74F543DW but differs in packaging and reel specifications. The F series offers higher speed than standard 74LS counterparts while maintaining TTL compatibility.
