(Note 2) The V_CC supply voltage to each TLP2631 isolator must be bypassed by a 0.01μF capacitor or larger. This
can be either a ceramic or solid tantalum capacitor with good high frequency characteristic and should
be connected as close as possible to the package V_CC and GND pins each device.
(Note 3) Device considered a two−terminal device: Pins 1, 2, 3 and 4 shorted together, and pins 5, 6, 7 and 8
shorted together.
(Note 4) CM_Hï½¥the maximum tolerable rate of rise of the common mode voltage to ensure the output will remain in
the high state (i.e., V_OUT > 2.0V).
Measured in volts per microsecond (V / μs).
Volts/ microsecond can be translated to sinusoidial voltages:

Example:
V_CM = 319V_pp when f_CM = 1MHz using CM_L and CM_H = 1000V / μs data sheet specified minimum.
(Note 5) CM_Lï½¥the maximum tolerable rate of fall of the common mode voltage to ensure the output will remain in
the low output state (i.e., V_OUT > 0.8V).
Measured in volts per microsecond (V / μs).
(Note 6) Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
