LOW-VOLTAGE 12-BIT 3:1  
MUX / DEMUX BUS SWITCH  
FEATURES:  
DESCRIPTION:  
• 5A/B bi-directional switch  
The CBTLV16214 provides a set of 12 high-speed buses switching  
betweenthreeseparateports. ThelowONresistanceallowsinputstobe  
connectedtooutputswithoutaddingpropagationdelay. TheCBTLV16214  
operates as a 12-bit bus select through the data select (S0-S2) terminals.  
• Isolation Under Power-Off Conditions  
• Over-voltage tolerant  
• Latch-up performance exceeds 100mA  
• VCC = 2.3V - 3.6V, normal range  
• ESD >2000V per MIL-STD-883, Method 3015; >200V using  
machine model (C = 200pF, R = 0)  
• Available in SSOP, TSSOP, and TVSOP packages  
APPLICATIONS:  
• Muxing and demuxing  
• 3.3V High Speed Bus Switching and Bus Isolation  
• Hot-swapping, hot-docking

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

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.
