Octal Bus Switches Offer Near-Zero Propagation Delay

Three octal bus switches have been developed that offer near-zero propagation delay. Organized as two 4-bit switches with separate OE signals, the FST3244 is pin compatible with standard logic 244 functions; the FST3245 is an 8-bit switch with flow through pinout for ease of layout and compatibility with standard 245 functions; and the FST3345 is an 8-bit switch with dual output enable pins and flow through pinout design for ease of layout. The devices are available in SOIC, QSOP and TSSOP packages.
