SN74LVTH540PW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH540PW is an octal buffer and line driver from Texas Instruments, belonging to the LVTH logic series. It features eight inputs and outputs with three-state capability and inverting polarity. The device operates within a supply voltage range of 2.7 V to 3.6 V. It provides high drive strength with a low-level output current of 64 mA and a high-level output current of -32 mA. Propagation delay is specified at 2.7 ns at 3.3 V. The component is housed in a TSSOP-20 package and supports surface mount installation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent buffering channels for parallel data lines
• Three-state outputs enable direct connection to bus structures without additional drivers
• Inverting logic polarity ensures signal phase reversal across all channels
• High drive capability supports heavy capacitive loads on system buses

Buffers, Drivers, Receivers, Transceivers Applications

• Parallel bus architectures requiring signal buffering and isolation
• Memory interface circuits utilizing three-state control
• Clock distribution networks needing high drive strength
• I/O port expansion in embedded systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the tube packaging format associated with the PW designation. Ensure compatibility with standard TSSOP-20 footprint dimensions during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an inverting octal buffer with three-state outputs is required for 3.3 V systems. Compare propagation delay specifications against other LVTH variants if timing constraints are critical. Consider the TSSOP-20 package size relative to available board space compared to SOIC alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH540 family of octal buffers. It shares functional similarities with non-inverting counterparts like the SN74LVTH541 but differs in logic polarity. The device complements other LVTH series components such as transceivers and latched drivers within Texas Instruments' logic portfolio.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVTH540PWR serves as a reel-based alternative with identical electrical characteristics. SN74LVTH540DWR offers the same functionality in a DW (SOIC) package variant.
