TC7MBD3245AFK  
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC7MBD3245AFK  
Octal Bus Switch  
The TC7MBD3245AFK 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.  
The device is enable to realize the shift of signal level from 5 V  
to 3.3 V.  
All inputs are equipped with protection circuits against static  
discharge.

Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even  
destruction.  
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the  
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even  
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum  
ratings and the operating ranges.  
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook  
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test  
report and estimated failure rate, etc).

Note 1: Typical values are at VCC = 5 V, Ta = 25°C.  
Note 2: It recommends that this device uses Pull-up resistance when adding and using resistance for  
an output terminal. Since it couses to drop a VOH voltage level when using Pull-down resistance  
for an output terminal.  
Note 3: Measured by the voltage drop between A and B pins at the indicated current through the switch. On  
resistance is determined by the lower of the voltages on the two (A or B) pins.
