CBT16292

CBT16292 12-bit 1-of-2 multiplexer/demultiplexer Rev. 02 — 18 April 2008 Product data sheet 1. General description The CBT16292 is a 12-bit 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer. The low ON resistance of the switch allows connections to be made with minimal propagation delay. When the select input (S) is LOW, port nA is connected to port nB1 and port nB2 is connected to GND via an internal pull-down resistor (500 Ω). When select input (S) is HIGH, port nA is connected to port nB2 and nB1 is connected to GND via an internal pull-down resistor (500 Ω). The CBT16292 is characterized for operation from –40 °C to +85 °C. 2.
