SN74LVTH543DBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH543DBR is an octal bus transceiver from the Texas Instruments SN74LVTH543 series, utilizing BiCMOS technology. It operates within a supply voltage range of 2.7 V to 3.6 V and supports LVTTL input and output logic levels. The device features non-inverting data transmission with three-state outputs and includes latched transceiver functionality. 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 is housed in a 24-SSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-24 tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the component meets the required industrial temperature specifications for the intended deployment environment before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring eight-bit wide data paths at 3.3V logic levels. The LVTH series offers faster switching speeds compared to standard LV families while maintaining lower power consumption than ABT counterparts. Ensure the target application board layout accommodates the 24-SSOP footprint dimensions.

Buffers, Drivers, Receivers, Transceivers Part Context
