1. Functional Description
•
Single 1-of-2 Multiplexer/Demultiplexer
2. General
The TC7SB3157CFU is a high-speed CMOS single 1-of-2 multiplexer/demultiplexer. The low ON resistance of
the switch allows connections to be made with minimal propagation delay time.
This device is 1 to 2 multiplexer/demultiplexer controlled by the select input (S). The A input is connected to B1
or B2 output based on the selection of Control input (S).
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).

11. Rise and Fall Time (t
r
/t
f
)
The t
r(out)
and t
f(out)
values of the output signals are affected by the CR time constant of the input, which consists
of the switch terminal capacitance (C
I/O
) and the on-resistance (R
ON
) of the input.
In practice, the t
r(out)
and t
f(out)
values are also affected by the circuit's capacitance and resistance components
other than the capacitance of TC7SB3157CFU
The t
r
/t
f(out)
values can be approximated as follows.
(Figure 11.1, Table 11.1 shows the test circuit.)
t

/t

(approx) = - (C

(R

ln (((V

- V

) - V

) / (V

- V

))
Where, R
DRIVE
is the output impedance of the previous-stage circuit.
Calculation example:
t
r(out)
(approx) = - (15 + 15) E - 12
(120 + 4)
ln (((4.5 - 0) - 2.25) / (4.5 - 0))

(output impedance of the previous IC), V

, low-level voltage = GND)
