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.

FEATURES

• High data rate, 1 MHz typical (NRZ)

•Free from latch up and oscilliation throughout voltage and temperature ranges.

• Microprocessor compatible drive

• Logic compatible output sinks 16 mA at 0.4 V maximum

• Guaranteed on/off threshold hysteresis

• Wide supply voltage capability, compatible with all popular logic systems

• Underwriters Laboratory (UL) recognized—file #E90700, Volume 2
