SN74LV245ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV245ADW is an octal bus transceiver manufactured by Texas Instruments, designed for asynchronous bidirectional data communication between buses. It operates within a supply voltage range of 2V to 5.5V and utilizes CMOS technology. The device features non-inverting logic with three-state outputs controlled by separate output enable (OE) and direction (DIR) inputs. It supports mixed-mode operation across all ports, allowing interface between different voltage domains. The component is housed in a 20-pin SOIC package and is rated for industrial temperatures from -40°C to +85°C.
