The SN74ALVC16501DL is a 18-bit universal bus transceiver with 3-state outputs from Texas Instruments. This device is designed to support signal translation between different voltage domains. It operates at 2.5V to 3.6V supply voltage and has 5V tolerant I/Os. The SN74ALVC16501DL features 18 independent bidirectional buffers that support mixed-mode signal operations such as push-pull, open-drain, and TTL-compatible. It also offers high drive strength, low power consumption, and fast switching speeds, making it suitable for a wide range of applications. The 3-state outputs are controlled by the output enable (OE) inputs, and the direction control (DIR) input controls the direction of data flow. The SN74ALVC16501DL is available in a TSSOP-56 package, making it easy to implement in various circuit designs
