16-bit 1-of-2 multiplexer/demultiplexer with precharged outputs and Schottky undershoot protection for live insertionFEATURES
5 typical ron Pull-up on B ports Undershoot protection on A port only: �1.5 V Near zero propagation delay Controlled enable rate VCC operating range: > 100 MHz bandwidth (or clock rate) 20 pF load capacitance 56-pin TSSOP package Bias voltage pre-charges the B output when the channel isAPPLICATION
The 16-bit 1-of-2 multiplexer/demultiplexer with precharged outputs and Schottky protection for live insertion. Advantages of the CBT6832 include a propagation delay of 250 ps, resulting from 5 channel resistance, and low I/O capacitance. A port demultiplexes to either 1B and or to both. The switch is bi-directional.

These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150�C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
