The CBT3T device clamps the output voltage to V_CC if the input voltage is higher than V_CC, or to V_CC − 1 V otherwise. Use it if you want this clamping.

The CBTLV is a plain analog switch using transmission gates. Use it for any signals ≤ V_CC.

See [FAQ] What are the Types of Architectures TI Switches and Multiplexers Use and how do I know which one my device has internally?
