Notes:
1. Measured at a point 1.6 mm below seating plane.
2. Current into/out of any single lead.
3. Surge input current duration is 3 ms at 120 Hz pulse repetition rate. Transient input current duration is 10
μ
s at 120 Hz pulse
repetition rate. Note that maximum input power, P
IN
, must be observed.
4. Derate linearly above 70
°
C free-air temperature at a rate of 4.1 mW/
°
C. Maximum input power dissipation of 230 mW allows an input
IC junction temperature of 125
°
C at an ambient temperature of T
A
= 70
°
C with a typical thermal resistance from junction to ambient
of
θ
JA1
= 240

C/W. Excessive P
IN
and T
J
may result in IC chip degradation.
5. Derate linearly above 70
°
C free-air temperature at a rate of 5.4 mW/
°
C.
6. Derate linearly above 70
°
C free-air temperature at a rate of 3.9 mW/
°
C. Maximum output power dissipation of 210 mW allows an
output IC junction temperature of 125
°
C at an ambient temperature of T
A
= 70
°
C with a typical thermal resistance from junction to
ambient of
θ
JA0
= 265
°
C/W.
7. Derate linearly above 70
°
C free-air temperature at a rate of 0.6 mA/
°
C.
8. Maximum operating frequency is defined when output waveform Pin 6 obtains only 90% of V
CC
with R
L
= 4.7 k
, C
L
= 30 pF using
a 5 V square wave input signal.
9. All typical values are at T
= 25
°
C, V
= 5.0 V unless otherwise stated.
10. The t
propagation delay is measured from the 2.5 V level of the leading edge of a 5.0 V input pulse (1
μ
s rise time) to the 1.5 V
level on the leading edge of the output pulse (see Figure 10).
11. The t
propagation delay is measured from the 2.5 V level of the trailing edge of a 5.0 V input pulse (1
μ
s fall time) to the 1.5 V
level on the trailing edge of the output pulse (see Figure 10).
12. Common mode transient immunity in Logic High level is the maximum tolerable (positive) dV
/dt on the leading edge of the
common mode pulse, V
, to insure that the output will remain in a Logic High state (i.e., V
> 2.0 V). Common mode transient
immunity in Logic Low level is the maximum tolerable (negative) dV
CM
/dt on the trailing edge of the common mode pulse signal,
V
, to insure that the output will remain in a Logic Low state (i.e., V
< 0.8 V). See Figure 11.
13. In applications where dV
/dt may exceed 50,000 V/
μ
s (such as static discharge), a series resistor, R
CC
, should be included to
protect the detector IC from destructively high surge currents. The recommended value for R
CC
is 240
per volt of allowable drop
in V
(between Pin 8 and V
) with a minimum value of 240
.
14. Logic low output level at Pin 6 occurs under the conditions of V
≥
V
TH+
as well as the range of V
> V
TH–
once V
has exceeded
V
. Logic high output level at Pin 6 occurs under the conditions of V
IN
≤
V
TH-
as well as the range of V
IN
< V
TH+
once V
IN
has
decreased below V
.
15. AC voltage is instantaneous voltage.
16. Device considered a two terminal device: Pins 1, 2, 3, 4 connected together, and Pins 5, 6, 7, 8 connected together.
17. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage
≥
3000 V rms for 1 second
(leakage detection current limit, I
i-o
≤
5
μ
A).
