The Texas Instruments SN74LS399 is a monolithic quadruple two-input multiplexer with storage. It provides the functional capabilities of two separate MSI functions in a single 16-pin package. The device selects one of two 4-bit data sources and stores data synchronously with the system clock. When the word-select input is low, word 1 is applied to the flip-flops. A high input to word select causes the selection of word 2. The selected word is clocked to the output terminals on the positive-going edge of the clock pulse.
This multiplexer is part of the LS technology family and offers a configuration of 8:4, 2:1 with 4 channels. It operates within a temperature range of 0°C to 70°C and has a typical power dissipation of 37 milliwatts. The SN74LS399 is housed in a PDIP (N) package.
Applications for the SN74LS399 include use as a dual source for operands and constants in arithmetic processors, releasing processor register files for acquiring new data, implementing separate registers capable of parallel exchange of contents, and as a universal type register for implementing various shift patterns.
