Description

These optocouplers consist of an AlGaAS LED, optically coupled to a very high speed integrated photo-detector logic gate. Devices include a strobable output. This output features an open collector, thereby permitting wired OR outputs. The coupled parameters are guaranteed over the temperature range of -40°C to +85°C. A maximum input signal of 5 mA will provide a minimum output sink current of 13 mA (fan out of 8). An internal noise shield provides superior common mode rejection of typically 50 kV/µs at 1,000V common mode.

Absolute Maximum Ratings

(No derating required up to 85°C)

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.

Notes

1. The V

supply to each optoisolator must be bypassed by a 0.1µF capacitor or larger. This can be either a ceramic

or solid tantalum capacitor with good high frequency characteristic and should be connected as close as possible to the package V

and GND pins of each device.
