The SN74ALS645A-1DWR is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features true logic with 3-state outputs, allowing data to be transmitted from the A bus to the B bus or vice versa, depending on the direction-control (DIR) input. The output-enable (OE) input can disable the device, effectively isolating the buses. This specific part number is characterized for operation within a temperature range of 0¬8C to 70¬8C and has a maximum low-level output current (IOL) of 48 mA, which is higher than the standard version. The device is available in a high-density 20-pin SOIC package, making it suitable for applications where space is a concern. The SN74ALS645A-1DWR is compliant with RoHS standards and is intended for use in various electronic applications requiring reliable data transmission.
