The SN74ABT640 is an octal bus transceiver designed for asynchronous communication between data buses. It features 3-state outputs and can transmit inverted data between two buses, A and B, based on the direction-control (DIR) input. The output-enable (OE) input allows for bus isolation when needed. This device operates within a supply voltage range of 4.5V to 5.5V and is characterized for temperatures from -40°C to 85°C. It provides high-drive outputs with a maximum output current of -32 mA for high-level outputs and 64 mA for low-level outputs. The device also includes robust ESD protection exceeding 2000V and latch-up performance exceeding 500 mA, ensuring reliability in various applications. The SN74ABT640 is available in multiple package options, including the 20-pin SOIC (DW), making it suitable for a range of design requirements. It is important to note that unused pins should be held high or low to prevent floating states.
