Notes:  
3. Derate linearly above 55 °C free-air  
temperature at a rate of 5.1 mW/ °C.

9. The fall time, tf, is measured from the  
1. Derate linearly above 55 °C free air  
temperature at a rate of 3.8 mW/ °C.  
Proper application of the derating  
factors will prevent IC junction  
temperatures from exceeding 125 °C  
for ambient temperatures up to 85 °C.  
2. Derate linearly above a free-air  
temperature of 70 °C at a rate of 2.3  
mW/ °C. A significant amount of  
power may be dissipated in the  
HCPL-4100 output circuit during the  
transition from the SPACE state to  
the MARK state when driving a data  
line or capacitive load (C OUT). The  
average power dissipation during the  
transition can be estimated from the  
following equation which assumes a  
linear discharge of a capacitive load:  
P = ISC (VSO + VMO)/2, where VSO is  
the output voltage in the SPACE  
state. The duration of this transition  
90% to the 10% level on the falling  
edge of the output current pulse.  
10. Common mode transient immunity in  
the logic high level is the maximum  
(positive) dVCM/dt on the leading  
edge of the common mode pulse,  
VCM, that can be sustained with the  
output in a Mark ("H") state (i.e.,  
IO > 12 mA).  
11. Common mode transient immunity in  
the logic low level is the maximum  
(positive) dVCM/dt on the leading  
edge of the common mode pulse,  
VCM, that can be sustained with the  
output in a Space ("L") state (i.e., IO  
< 3 mA).  
12. Use of a 0.1 µF bypass capacitor  
connected between pins 5 and 8 is  
recommended.  
13. In accordance with UL 1577, each  
optocoupler is momentary withstand  
proof tested by applying an insulation  
test voltage 3000 V rms for 1  
second (leakage detection current  
limit, Ii-o 5 µA).  
into the output in the mark state (I  
is internally limited to protect the  
device. The duration of the output  
)
SC  
short circuit shall not exceed 10 ms.  
5. The device is considered a two  
terminal device, pins 1, 2, 3, and 4  
are connected together, and pins 5,  
6, 7, and 8 are connected together.  
6. The tPLH propagation delay is  
measured from the 1.3 volt level on  
the leading edge of the input pulse to  
the 10 mA level on the leading edge  
of the output pulse.  
7. The tPHL propagation delay is  
measured from the 1.3 volt level on  
the trailing edge of the input pulse to  
the 10 mA level on the trailing edge  
of the output pulse.  
8. The rise time, t r, is measured from the  
10% to the 90% level on the rising  
edge of the output current pulse.  
can be estimated as t = C OUT (VSO  
VMO)/ISC. For typical applications  
driving twisted pair data lines with  
NRZ data as shown in Figure 11, the  
transition time will be less than 10%  
of one bit time.
