The Texas Instruments SN74LVT245DWR is an octal bus transceiver designed for bidirectional asynchronous communication between two data buses. It is used in board-level signal buffering, level translation, and bus isolation in systems like industrial controllers, telecom line cards, and computing peripherals where the LVT family's 3.3 V operation and 5 V tolerant inputs are needed.
If your design must meet RoHS directives for EU or similar markets, this part cannot be used in standard commercial products. It remains suitable for military, aerospace, or legacy industrial applications where RoHS exemptions apply or are not required.
Package and rework considerations
The package is a standard SOIC-20 (body width 7.5 mm) with a 1.27 mm pitch — easy to hand-solder or rework with hot air. Will it survive the hot air? Yes, with a standard 260 °C peak reflow profile and a pre-bake if the moisture barrier bag has been open.
