Microprocessor compatible photo coupler NQUNXIN QXH11L1-CuH-S with guaranteed on off threshold hysteresis
Product Description
The QXH11LX series of devices features a GaAs infrared emitting diode optically coupled to a high-speed integrated circuit detector. The output detector incorporates a Schmitt trigger, providing hysteresis for noise immunity and pulse shaping. These high-speed photo couplers offer a typical data rate of 2MHz (NRZ), are free from latch-up and oscillation across voltage and temperature ranges, and are microprocessor compatible. They feature logic-compatible outputs that sink 16mA at 0.4V maximum, guaranteed on/off threshold hysteresis, and wide supply voltage capability compatible with popular logic systems. The operating temperature range is -55C to 100C. Applications include logic-to-logic isolation, programmable current level sensing, line receivers for noise and transient elimination, and AC to TTL conversion with square wave shaping.
