Renesas Electronics QS3251QG8, Bus Switch, 8:1

The Renesas Electronics mux-demux is a high-speed CMOS TTL-compatible 8:1 multiplexer/ demultiplexer. The mux-demux has 3-state outputs. The mux-demux is a function and pinout compatible version of the 74F251, 74FCT251 and the 74ALS/ AS/LS251 8:1 multiplexers. The low ON resistance of the mux-demux allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. Mux/Demux devices provide an order of magnitude faster speed than equivalent logic devices. The mux-demux is characterized for operation at -40C to +85C.
