SN74LV245ATPWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ATPWT is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous bidirectional data communication between two buses. It operates within a supply voltage range of 2V to 5.5V and features three-state outputs. The device includes direction control (DIR) and output enable (OE) inputs to manage data flow and isolate the bus. It supports mixed-mode operation on all ports, allowing simultaneous use of different voltage levels. Key electrical characteristics include a maximum propagation delay of 6.5ns at 5V and high electrostatic discharge protection ratings.
