The Texas Instruments SN74ALS990DW is an octal D-type transparent read-back latch designed for storing data bus contents with read-back capability. This device features eight transparent D-type latches where the Q outputs follow the D inputs when the latch-enable (LE) is high. Read-back is enabled through the output-enable (OE) input.
Key electrical specifications include a maximum clock frequency of 75 MHz, an IOL of 24 mA, and an IOH of 2.6 mA. The supply current is a maximum of 70000 µA. The operating voltage range is 4.5V to 5.5V, and it operates within a temperature range of 0°C to 70°C.
This latch is housed in a 20-SOIC package with a surface mount type. The flow-through pinout and high-speed operation make it suitable for various logic applications requiring data storage and retrieval. The output type is Tri-State, and it has a propagation delay of 6 ns.
The SN74ALS990DW is characterized for operation from 0°C to 70°C. It is designed for storing the contents of the input data bus and providing the capability of reading back the stored data onto the input data bus.
