SN74LS399

具有存儲器的四路 2 輸入多路復(fù)用器; ? Single-Rail Outputs on 'LS399? Selects One of Two 4-Bit Data Sources and Stores Data Synchronously with System Clock? Applications:? Dual Source for Operands and Constants in Arithmetic Processor; Can Release Processor Register Files for Acquiring New Data? Implement Separate Registers Capable of Parallel Exchange of Contents Yet Retain External Load Capability? Universal Type Register for Implementing Various Shift Patterns: Even Has Compound Left-Right Capabilities;

This monolithic quadruple two-input multiplexer with storage provides essentially the equivalent functional capabilities of two separate MSI functions (SN54LS157/SN74LS157 and SN54LS175/SN74LS175) in a single 16-pin package. When the word-select input is low, word 1 (A1, B1, C1, D1) is applied to the flip-flops. A high input to word select will cause the selection of word 2 (A2, B2, C2, D2). The selected word is clocked to the output terminals on the positive-going edge of the clock pulse. Typical power dissipation is 37 milliwatts. The SN54LS399 is characterized for operation over the full military range of -55°C to 125°C. The SN74LS399 is characterized for operation from 0°C to 70°C. ? \n
