** 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 refers to your equipment level safety speci cation or Avago Application Note 1074 entitled
“Optocoupler Input-Output Endurance Voltage.”
Notes:
1. Derate linearly above 70°C free-air temperature at a rate of 0.3 mA /°C.
2. Maximum pulse width = 10 μs.
3. Derate linearly above 70° C free-air temperature at a rate of 4.8 mW /°C.
4. Derate linearly above 70° C free-air temperature at a rate of 5.4 mW /°C. The maximum LED junction temperature should not exceed 125°C.
5. Maximum pulse width = 50 μs
6. In this test VOH is measured with a dc load current. When driving capacitive loads VOH will approach V
CC
as I
OH
approaches zero amps.
7. Maximum pulse width = 1 ms
8. This load condition approximates the gate load of a 1200 V/100A IGBT.
9. Pulse Width Distortion (PWD) is de ned as |t
PHL
- t
PLH
| for any given device.
10. The di erence between t
PHL
and t
PLH
between any two ACPL-T350 parts under the same test condition.
11. Pins 1 and 4 need to be connected to LED common.
12. Common mode transient immunity in the high state is the maximum tolerable dV
CM
/dt of the common mode pulse, V
CM
, to assure that the
output will remain in the high state (i.e., V
O
> 15.0 V).
13. Common mode transient immunity in a low state is the maximum tolerable dVCM/dt of the common mode pulse, V
CM
, to assure that the output
will remain in a low state (i.e., V
O
< 2.0 V).
14. In accordance with UL1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 4500 Vrms for 1 second (leakage detection
current limit, I
I-O
≤ 5 μA).
15. Device considered a two-terminal device: pins 1, 2, 3, and 4 shorted together and pins 5, 6, 7, and 8 shorted together.
