Rochester Electronics Logic - Buffers, Drivers, Receivers, Transceivers SN74ALS620ADW

The SN74ALS620ADW is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features a dual-enable configuration that allows for maximum flexibility in data transmission, enabling data transfer from the A bus to the B bus or vice versa, depending on the logic levels at the output-enable inputs (OEAB and OEBA). The device supports both true and inverting logic, with the SN74ALS620A variant providing inverting outputs. This transceiver is characterized for operation within a temperature range of 0¬8C to 70¬8C and is available in a 20-pin SOIC package. It has a maximum supply voltage of 7V and can handle input voltages up to 7V, with I/O ports rated at 5.5V. The device is suitable for applications requiring local bus-latch capability and can effectively isolate buses when disabled. The SN74ALS620ADW is part of a series that includes other variants with different output configurations, providing options for various design needs.
