Texas Instruments Logic - Logic - Buffers, Drivers, Receivers, Transceivers - SN74ABTH245DWR SN74ABTH245DWR

The SN74ABTH245DWR is an octal bus transceiver designed for asynchronous communication between data buses. It features high-drive outputs with a maximum output current of 32 mA for high-level outputs and 64 mA for low-level outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and is characterized for temperatures from -40¬8C to 85¬8C. This transceiver includes active bus-hold circuitry that maintains valid logic levels on unused or floating data inputs, eliminating the need for external pull-up or pull-down resistors. It supports hot insertion with Ioff and power-up 3-state capabilities, ensuring outputs are disabled during power down to prevent backflow currents. The device is available in various package options, including a 20-SOIC package, making it suitable for surface mount applications. Engineers considering this product should note its compliance with halogen-free standards and its medium popularity in the market, along with a limited supply and demand status.
