Note 2: 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.

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 TC7WB66CFK/L8X, TC7WB67CFK/L8X
The t
r
/t
f(out)
values can be approximated as follows.
(Figure 12.1, Table 12.1 shows the test circuit.)

(approx) = - (C

+ R

) ln (((V

- V

) - V
M
) / (V

- V

))
Where, R
DRIVE
is the output impedance of the previous-stage circuit.
Calculation example:
t
r(out)
(approx) = - (10 + 15) E - 12 (120 + 4) ln (((4.5 - 0) - 2.25) / (4.5 - 0)) = ≈2.1 ns
Calculation conditions:
V
CC
= 4.5 V, C
L
= 15 pF, R
DRIVE
= 120 Ω (output impedance of the previous IC), V
M
= 2.25 V (V
CC
/2)
Output of the previous IC = digital (i.e., high-level voltage = V
CC
, low-level voltage = GND)
