Description
The H11LXM series has a high-speed integrated circuit
detector optically coupled to a gallium-arsenide infrared
emitting diode. The output incorporates a Schmitt trigger,
which provides hysteresis for noise immunity and pulse
shaping. The detector circuit is optimized for simplicity of
operation and utilizes an open-collector output for
maximum application flexibility.

Absolute Maximum Ratings
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. TA = 25°C unless otherwise specified.

Note:
2. Maximum IF(ON) is the maximum current required to trigger the output. For example, a 1.6 mA maximum trigger current would
require the LED to be driven at a current greater than 1.6 mA to guarantee the device turns on. A 10% guard band is recommended
to account for degradation of the LED over its lifetime. The maximum allowable LED drive current is 30 mA.
