The SN54LS399J from Texas Instruments is a monolithic quadruple two-input multiplexer with storage, designed for applications requiring selection and storage of data synchronously with a system clock. This component effectively combines the functionality of separate multiplexer and storage functions into a single 16-pin CDIP (J) package.
Key electrical characteristics include a typical power dissipation of 37 milliwatts. The device selects one of two 4-bit data sources based on a word-select input and clocks the selected data to the output terminals on the positive-going edge of the clock pulse. The operating temperature range for the SN54LS399J is specified from -55°C to 125°C, making it suitable for military applications.
Applications for the SN54LS399J include use as a dual source for operands and constants in arithmetic processors, releasing processor register files for new data, and implementing separate registers capable of parallel exchange of contents. It also serves as a universal type register for implementing various shift patterns, including compound left-right capabilities.
The SN54LS399J is packaged in a 16-pin CDIP (J) with a standard package quantity of 25 units per tube. The lead finish is SnPb.
