General description
The CBT3257A is a quad 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer. The low ON resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. Output enable (OE) and select-control (S) inputs select the appropriate nB1 and nB2 outputs for the nA input data. The CBT3257A is characterized for operation from−40°Cto+85°C.
