SN74LVTH543DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH543DWR is an octal bus transceiver from the Texas Instruments SN74LVTH 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 provides a propagation delay of 2.5 ns, with a low-level output current capability of 64 mA and a high-level output current of -32 mA. It supports LVTTL input and output levels and functions as a non-inverting latched transceiver. Packaged in SOIC-24, it is rated for operation between -40°C and +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against design requirements, as the DWR suffix indicates tape-and-reel packaging. Confirm that the 2.7V to 3.6V operating range aligns with the target system power rails. Ensure compatibility with LVTTL logic levels for both input and output interfaces to maintain signal integrity in mixed-voltage environments.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage operation with moderate speed and high drive strength. The LVTH series offers improved performance over standard CMOS logic while maintaining compatibility with TTL-compatible inputs. Consider the SOIC-24 package dimensions and thermal characteristics during PCB layout planning.
