The CBTLV16214 provides a set of 12 high-speed buses switching
between three separate ports. The low ON resistance allows inputs to be
connected to outputs without adding propagation delay. The CBTLV16214
operates as a 12-bit bus select through the data select (S0-S2) terminals.
APPLICATIONS:
• Muxing and demuxing
• 3.3V High Speed Bus Switching and Bus Isolation
• Hot-swapping, hot-docking

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

NOTES:
1. Typical values are at 3.3V, +25°C ambient.
2. The increase in supply current is attributable to each input that is at the specified voltage level rather than VCC or GND.
3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch.
