VOH = (VCC – VEE) – (IOH x RDS(ON)).
This guarantees operation at IO peak minimum = 2.0A for -40°C to +100°C operating temperature range.

The output currents IOH and IOL are specified with a capacitive current limited load = (3 x 0.01µF) + 40Ω,
frequency = 8kHz, 50% DF. The maximum pulse width of the output current is 1.5µs, maximum duty cycle = 2.4%.
Output currents specified for different values of VDS for VCC – VEE = 20V with the formula:
VOL = (VCC – VEE) – (IOL x RDS(ON)).
This guarantees operation at IO peak minimum = 0.5A for -40°C to +100°C operating temperature range.

No derating required across operating temperature range.
In this test, VOH is measured with a dc load current. When driving capacitive load VOH will approach VCC as IOH
approaches zero amps.
Maximum pulse width = 1ms, maximum duty cycle = 20%.
tPHL propagation delay is measured from the 50% level on the falling edge of the input pulse to the 50% level of the
falling edge of the VO signal. tPLH propagation delay is measured from the 50% level on the rising edge of the input
pulse to the 50% level of the rising edge of the VO signal.
Pin 1 and 4 need to be connected to LED common.
Common mode transient immunity in the high state is the maximum tolerable dVCM/dt of the common mode pulse
VCM to assure that the output will remain in the high state (i.e. VO > 10.0V).
10. Common mode transient immunity in a low state is the maximum tolerable dVCM/dt of the common mode pulse,
VCM, to assure that the output will remain in a low state (i.e. VO < 1.0V).
11. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000Vrms
for 1 second (leakage detection current limit II-O < 5µA).
12. Device considered a two-terminal device: pins on input side shorted together and pins on output side shorted
together.

• One time soldering reflow is recommended
Output Power Derating
The output power is the product of the average output current
squared times the output transistor’s RDS(ON):
The maximum package power dissipation is 295mW. The package is limited to this level to ensure that under normal operating
conditions and over extended temperature range that the semiconductor junction temperatures do not exceed 125°C. The
package power is composed of three elements; the LED, static
operating power of the output IC, and the power dissipated in
the output power MOSFET transistors. The power rating of the
output IC is 250mW. This power is divided between the static
power of the integrated circuit, which is the product of IDD times
the power supply voltage (VDD – VEE). The maximum IC static
output power is 150mW, (VDD – VEE) = 25V, IDD = 6mA. This
maximum condition is valid over the operational temperature
range of -40°C to +100°C. Under these maximum operating
conditions, the output of the power MOSFET is allowed to dissipate 100mW of power.
PO(AVG) = IO(AVG)2 • RDS(ON)
The IO(AVG) is the product of the duty factor times the peak
current flowing in the output. The duty factor is the ratio of the
‘on’ time of the output load current divided by the period of the
operating frequency. An RDS(ON) of 2.0Ω results in an average
output load current of 200mA. The load duty factor is a ratio of
the average output time of the power MOSFET load circuit and
period of the driving frequency.
The maximum permissible, operating frequency is determined
by the load supplied to the output at its resulting output pulse
width. Figure 13 shows an example of a 0.03µF gate to source
capacitance with a series resistance of 40Ω. This reactive load
results in a composite average pulse width of 1.5µs. Under this
load condition it is not necessary to derate the absolute maximum output current out to 250kHz.
The absolute maximum output power dissipation versus ambient temperature is shown in Figure 12. The output driver is
capable of supplying 100mW of output power over the temperature range from -40°C to 87°C. The output derates to 90mW at
the absolute maximum operating temperature of 100°C.

Reflow Profile
This device is tested and specified when driving a complex
reactive load. The load consists of a capacitor in the series with
a current limiting resistor. The capacitor represents the gate to
source capacitance of a power MOSFET transistor. The test
load is a 0.03uF capacitor in series with an 40Ω resistor. The
LED test frequency is 10.0kHz with a 50% duty cycle. The combined IOH and IOL output load current duty factor is 0.6% at the
test frequency.
Figure 14 illustrates the relationship of the LED input drive
current and the device’s output voltage and sourcing and sinking currents. The 0.03µF capacitor load represents the gate to
source capacitance of a very large power MOSFET transistor.
A single supply voltage of 20V is used in the evaluation.
Figure 15 shows the test schematic to evaluate the output voltage and sourcing and sinking capability of the device. The IOH
and IOL are measured at the peak of their respective current
pulses.
