The TC7MBL3125C and TC7MBL3126C are a Low Voltage/Low
Capacitance CMOS 4bit Bus Switch. The low on-resistance of the
switch allows connections to be made with minimal propagation
delay time.
The TC7MBL3125C requires the output enable (
) input to be
OE
set high to place the output into the high impedance state,whereas
the TC7MBL3126C requires the output enable (OE) input to be set
low to place the output into the high impedance.
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).

Rise and Fall Times (tr / tf) of the TC7MBL3125C 3126C 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 TC7MBL3125C, 3126C.
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
