Texas Instruments Buffers, Drivers, Receivers, Transceivers SNJ54ABTH245W

The SNJ54ABTH245W is an octal bus transceiver designed for asynchronous communication between data buses. It features 3-state outputs 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 includes an output-enable (OE) input for bus isolation and is characterized for operation over a military temperature range of -55¬8C to 125¬8C. This transceiver incorporates high-drive outputs, with a typical output current of -32 mA for high-level outputs and 64 mA for low-level outputs. It also features bus hold circuitry on data inputs, which eliminates the need for external pull-up or pull-down resistors. The device supports hot insertion with Ioff and power-up 3-state functionality, ensuring that outputs are disabled during power down to prevent backflow current. The SNJ54ABTH245W is available in various package options, including ceramic flat (W) and LCCC (FK) packages, making it suitable for different application requirements. Its robust design and specifications make it a reliable choice for engineers looking for a high-performance bus transceiver.
