description/ordering information  
The SN74CBTK32245 provides 32 bits of high-speed TTL-compatible bus switching. The low on-state  
resistance of the switch allows connections to be made with minimal propagation delay.  
The A and B ports have an active-clamp undershoot-protection circuit. When there is an undershoot, the  
active-clamp circuit is enabled and current from V  
transistor from turning on.  
is supplied to clamp the output, preventing the pass  
CC  
The device is organized as four 8-bit bus switches, two 16-bit bus switches, or one 32-bit bus switch. When the  
output-enable (OE) input is low, the switch is on and port A is connected to port B. When OE is high, the switch  
is open and the high-impedance state exists between the two ports.  
This device is fully specified for partial-power-down applications using I . The I circuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.
