Quad 1-of-2 multiplexer/demultiplexer
Rev. 04 — 19 March 2009
Product data sheet
1. 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 °C to +85 °C.
2. Features
