description/ordering information  
The SN74CBT3384C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (r ),  
on  
allowing for minimal propagation delay. Active Undershoot-Protection Circuitry on the A and B ports of the  
SN74CBT3384C provides protection for undershoot up to −2 V by sensing an undershoot event and ensuring  
that the switch remains in the proper OFF state.  
The SN74CBT3384C is organized as two 5-bit bus switches with separate output-enable (1OE, 2OE) inputs.  
It can be used as two 5-bit bus switches or as one 10-bit bus switch. When OE is low, the associated 5-bit bus  
switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. When  
OE is high, the associated 5-bit bus switch is OFF, and the high-impedance state exists between the A and B  
ports.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
