Texas Instruments Integrated Circuits (ICs) - Logic - Buffers, Drivers, Receivers, Transceivers SN74ABTH245DGVRG4

The SN74ABTH245DGVRG4 is an octal bus transceiver designed for asynchronous communication between data buses. It features a 3-state output and can transmit data from the A bus to the B bus or vice versa, depending on the logic level at the direction-control (DIR) input. The device supports hot insertion with Ioff and power-up 3-state capabilities, ensuring outputs are disabled during power down to prevent backflow current. This transceiver operates with a supply voltage range of 4.5V to 5.5V and is characterized for temperatures from -40¬8C to 85¬8C. It has high-drive outputs, capable of sourcing 32mA and sinking 64mA, making it suitable for various applications. The active bus-hold circuitry maintains valid logic levels on unused or floating data inputs, eliminating the need for external pull-up or pull-down resistors. The device is available in a 20-TVSOP package and is suitable for surface mount technology (SMT) applications.
