1. General description
2. Features
3. Ordering information
The CBT3257A is a quad 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer.
The low ON-state 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 C to +85 C.
