OPTOISOLATORS LOGIC OUTPUT
H11L1M
DESCRIPTION
The H11LX series has a high speed integrated circuit
detector optically coupled to a gallium-arsenide infrared
emitting diode. The output incorporates a Schmitt trig-
ger, which provides hysteresis for noise immunity and
pulse shaping. The detector circuit is optimized for sim-
plicity of operation and utilizes an open collector output
for maximum application flexibility.

NOTE:
*Maximum I
F(ON)
is the maximum current required to trigger the output. For example, a 1.6mA maximum trigger current would require
the LED to be driven at a current greater than 1.6mA to guarantee the device will turn on. A 10% guard band is recommended to
account for degradation of the LED over its lifetime. The maximum allowable LED drive current is 60mA.
