The SN74ALS666DW is an 8-bit D-type transparent latch designed for storing input data and providing read-back capabilities. It features a 3-state output, making it suitable for bus-structured applications. The latch enables data to be passed from the D inputs to the Q outputs while the latch enable (LE) is high. The device also includes preset and clear inputs for additional control. The output can be isolated from the data bus using the read-back control (OERB) input, which allows for flexible data management. The SN74ALS666DW operates within a temperature range of 0¬8C to 70¬8C and is available in a 24-pin plastic small-outline package (DW).
