*Ratings apply to all devices except otherwise noted in the Package column.
**The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output
continuous voltage rating. For the continuous voltage rating refer to the VDE 0884 Insulation Characteristics Table (if applicable),
your equipment level safety specification or HP Application Note 1074 entitled “Optocoupler Input-Output Endurance Voltage.”
†For 8-pin DIP package devices (HCPL-261A/261N/263A/263N) only.
Notes:
1. Peaking circuits may be used which
produce transient input currents up
to 30 mA, 50 ns maximum pulse
width, provided the average current
does not exceed 10 mA.
2. 1 minute maximum.
3. Derate linearly above 80°C free-air
temperature at a rate of 2.7 mW/°C
for the SOIC-8 package.
4. Each channel.
5. Device considered a two-terminal
device: Pins 1, 2, 3, and 4 shorted
together and Pins 5, 6, 7, and 8
shorted together.
6. In accordance with UL1577, 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 µA).
This test is performed before the
100% production test for partial
discharge (method b) shown in the
VDE 0884 Insulation Characteristics
Table, if applicable.
7. In accordance with UL1577, each
optocoupler is proof tested by
applying an insulation test voltage
≥ 6000 V_RMS for 1 second (leakage
detection current limit, I_I-O ≤ 5 µA).
8. Measured between the LED anode and
cathode shorted together and pins 5
through 8 shorted together.
9. The t_PLH propagation delay is
measured from the 1.75 mA point on
the falling edge of the input pulse to
the 1.5 V point on the rising edge of
the output pulse.
10. The t_PHL propagation delay is
measured from the 1.75 mA point on
the rising edge of the input pulse to
the 1.5 V point on the falling edge of
the output pulse.
11. Propagation delay skew (t_PSK) is
equal to the worst case difference in
t_PLH and/or t_PHL that will be seen
between any two units under the
same test conditions and operating
temperature.
12. Single channel products only (HCPL-
261A/261N/061A/061N).
13. Common mode transient immunity in
a Logic High level is the maximum
tolerable |dV_CM/dt| of the common
mode pulse, V_CM, to assure that the
output will remain in a Logic High
state (i.e., Vo > 2.0 V).
14. Common mode transient immunity in
a Logic Low level is the maximum
tolerable |dV_CM/dt| of the common
mode pulse, V_CM, to assure that the
output will remain in a Logic Low
state (i.e., V_O < 0.8 V).
15. For sinusoidal voltages
(|dV_CM/dt|)max = πf_CM V_CM(P-P).
16. Bypassing of the power supply line is
required with a 0.1 µF ceramic disc
capacitor adjacent to each optocoup-
ler as shown in Figure 19. Total lead
length between both ends of the
capacitor and the isolator pins should
not exceed 10 mm.
17. Pulse Width Distortion (PWD) is
defined as the difference between
t_PLH and t_PHL for any given device.
18. No external pull up is required for a
high logic state on the enable input of
a single channel product. If the V_E pin
is not used, tying V_E to V_CC will result
in improved CMR performance.
19. Measured between pins 1 and 2
shorted together, and pins 3 and 4
shorted together. For dual channel
parts only.
