TC7MBL3245SFT/FK/FTG
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MBL3245SFT, TC7MBL3245SFK, TC7MBL3245SFTG
Low Voltage/Low Capacitance Octal Bus Switch
The TC7MBL3245S provides eight bits of low- voltage,
high-speed bus switching in a standard ’245 device pinout.
The low ON-resistance of the switch allows connections to be made
with minimal propagation delay and while maintaining CMOS low
power dissipation.
TC7MBL3245SFT
The device comprises a single 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 to guard 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).

Rise and Fall Times (tr / tf) of the TC7MBL3245S I/O Signals
The tr(out) and tf(out) values of the output signals are affected by the CR time constant of the input, which consists of
the switch terminal capacitance (C ) and the on-resistance (R ) of the input.
I/O ON
In practice, the tr(out) and tf(out) values are also affected by the circuit’s capacitance and resistance components other
than those of the TC7MBL3245S.
The tr(out) / tf(out) values can be approximated as follows. (Figure 3 shows the test circuit.)
tr(out) / tf(out) (approx) = - ( C + C ) ･ (R
