SN74LVTH543DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH543DW is an octal bus transceiver from the Texas Instruments SN74LVTH543 series, designed for low-voltage applications. It operates within a supply voltage range of 2.7 V to 3.6 V and features three-state outputs. The device supports LVTTL input and output levels, ensuring compatibility with standard logic families. Key electrical parameters include a propagation delay of 2.5 ns, a maximum power supply current of 5 mA, and output drive capabilities of -32 mA (high) and 64 mA (low). It is housed in a 24-pin SOIC package and functions as a non-inverting latched transceiver.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the design accommodates the specified 2.7 V to 3.6 V operating range and thermal requirements for the industrial temperature grade if applicable.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring octal bus interfacing at 3.3 V logic levels. It serves as a functional alternative to higher-voltage F-series transceivers when lower power consumption and voltage compatibility are priorities. Compare propagation delays and drive currents against system timing constraints to ensure signal integrity is maintained across the bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH543 family of octal bus transceivers. It shares architectural similarities with the SN74LVTH541 (buffer/driver) and SN74LVTH540 (inverting buffer), differing primarily in its bidirectional transceiver functionality and latching feature. The DW suffix denotes the plastic small-outline package, distinguishing it from TSSOP or SSOP variants within the same logical family.
