description/ordering information  
The SN74CBT3245C 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  
SN74CBT3245C 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 SN74CBT3245C is organized as an 8-bit bus switch with a single output-enable (OE) input. When OE is  
low, the 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 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.
