The SN74ALS990N from Texas Instruments is an octal D-Type transparent 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 functionality 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 device operates with a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 70000 µA. The propagation delay is specified at 6 ns.
This latch is characterized for operation within a temperature range of 0°C to 70°C. It is available in a 20-PDIP package and supports through-hole mounting. The technology family is ALS, with bipolar input type and 3-State output type. The pinout is described as bus-structured, and it offers true logic outputs.
The SN74ALS990N is designed for applications requiring data storage and retrieval from a bus. Its features like flow-through pinout and high speed make it suitable for various digital logic systems.
