SN74LVTH543NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH543NS is an octal registered transceiver manufactured by Texas Instruments, belonging to the LVTH logic series. It features BiCMOS technology with non-inverting polarity and three-state outputs. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports LVTTL input and output levels. Key electrical parameters include a propagation delay of 2.5 ns, a maximum power supply current of 5 mA, low-level output current of 64 mA, and high-level output current of -32 mA. It functions as a latched transceiver in a 24-pin SOIC package, suitable for surface mount installation across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal registered transceiver architecture providing eight-bit data storage and transfer capabilities
• Three-state outputs enabling direct connection to bus-oriented systems without additional drivers
• LVTTL compatible input and output levels ensuring interoperability with standard logic families

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and register implementations
• Clocking data registers and buffers
• Bidirectional bus translation between different logic domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation matches the required footprint, as the NS suffix indicates a 24-pin SOIC package distinct from TSSOP or PW variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 2.7 V to 3.6 V supply voltage range and LVTTL signaling requirements for reliable operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal registered transceiver with three-state outputs is required for bidirectional data transfer. The LVTH series offers improved performance over standard LVT counterparts while maintaining LVTTL compatibility. Consider the 24-pin SOIC package constraints and verify thermal management needs for the -40°C to +85°C operating range during system design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH543 family of 3.3-V ABT octal registered transceivers. It serves as a successor or variant to older LVT543 devices, offering enhanced switching characteristics. The NS package variant specifically denotes the small-outline integrated circuit form factor, distinguishing it from tape-and-reel or thin-shrink small-outline packages within the same logical function set.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVTH543PW is a verified substitute offering identical logical functionality in a TSSOP-24 package. SN74LVTH543DWR provides the same specifications in an SOIC-24 package but utilizes tape-and-reel packaging instead of tube. Verify pinout compatibility and physical dimensions before substituting.
