TC7MB3245FK  
Toshiba CMOS Digital Integrated Circuit Silicon Monolithic  
TC7MB3245FK  
Octal Bus Switch  
The TC7MB3245FK provides eight bits of high-speed  
TTL-compatible bus switching in a standard ’245 device pinout.  
The low on-state resistance of the switch allows connections to be  
made with minimal propagation delay.  
The device is organized as one 8-bit switch. When output  
enable (OE) is low, the switch is on and port A is connected to  
port B. When OE is high, the switch is open and a  
high-impedance state exists between the two ports.  
All inputs are equipped with protection circuits against static  
discharge.
