* The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous

voltage rating.

Notes:

1. Gain is defined as the slope of the best-fit line of differential output voltage (VOUT+ - VOUT-) versus input voltage over the nominal range, with offset

error adjusted. 0.5% Gain tolerance for ACPL-C87BT and 1% tolerance for ACPL-C87AT.

2. Common mode transient immunity (CMTI) is tested by applying a fast rising/falling voltage pulse across GND1 (pin 4) and GND2 (pin 5). The output

glitch observed is less than 0.2 V from the average output voltage for less than 1

ms.

3. Device considered a two terminal device: pins 1, 2, 3 and 4 shorted together, and pins 5, 6, 7 and 8 shorted together.

4. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 VRMS for 1 second.

5. Noise is measured at the output of the differential to single ended post amplifier.
