SN74LVTH543PWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH543PWRE4 is an octal registered bus transceiver from Texas Instruments, belonging to the LVTH logic series. It operates within a supply voltage range of 2.7 V to 3.6 V and features three-state outputs. The device utilizes BiCMOS technology and supports LVTTL input and output levels. Key electrical parameters include a propagation delay of 2.5 ns, a low-level output current of 64 mA, and a high-level output current of -32 mA. It is housed in a 24-TSSOP package and functions as a non-inverting latched transceiver with a maximum power supply current of 5 mA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance status according to manufacturer documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range aligns with system environmental constraints. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring registered bus interfaces at 3.3 V logic levels. The LVTH series offers faster switching speeds compared to standard LVC devices while maintaining compatible voltage levels. Consider the TSSOP-24 package size for space-constrained layouts. Evaluate the 64 mA sink capability against load requirements to ensure signal integrity across the bus.
