SNFA, SNFA QUADRUPLE -LINE TO -LINE DATA SELECTORS/MULTIPLEXERS SDFS0A MARCH 8 REVISED OCTOBER Buffered Inputs and Outputs Package Optio Include Plastic Small-Outline Packages, Ceramic Chip Carriers, and Standard Plastic and Ceramic 00-mil DIPs description The FA is a quadruple -input data selector/multiplexer featuring a common strobe () input. When the strobe is high, all outputs are low. When the strobe is low, a -bit word is selected from one of two sources and is routed to the four outputs. The FA provides true data. The SNFA is characterized for operation over the full military temperature range of C to C. The SNFA is characterized for operation from 0 C to 0 C.
