The SN74LVC4245APW with Bus Transceivers Octal Bus Trncvr & 3.3-5V W/3-St Otpt manufactured by Texas Instruments is a high-speed, low-voltage 8-bit bus transceiver. This device has an octal bus transceiver with three-state outputs, and two separate buses. It is capable of full or partial-word communication between data buses, with selectable direction for each of its four ports. It has five power supply and output voltage ranges of 3.3V to 5V, low average power consumption, low ground bounce, and high speed 5V-tolerant inputs on either side. The input and output levels are TTL-compatible and allow direct interfacing with 5V, 3.3V, and even 2.5V devices. The device also features power-off glitch free operation, three-state outputs for increased bus drive, and an open-drain output feature that allows it to be used as a wired-AND connection.
