1 HCPL-576x, 5962-8947701 AC/DC to Logic Interface Hermetically Sealed Optocouplers Data Sheet Description Features These devices are single-channel, hermetically sealed, Dual marked with device part number and DLA Standard voltage/current threshold detection optocouplers. The Microcircuit Drawing (SMD) products are capable of operation and storage over the full Manufactured and tested on a MIL-PRF-38534 certified line military temperature range and can be purchased as either QML-38534, Class H and K commercial product, or with full MIL-PRF-38534 Class Level H Hermetically sealed 8-pin dual in-line packages or K testing, or from the DLA Standard Microcircuit Drawing Performance guaranteed over 55C to +125C (SMD) 5962-89477. All devices are manufactured and tested on AC or DC input a MIL-PRF-38534 certified line, and Class H and K devices are included in the DLA Qualified Manufacturers List, QML-38534 Programmable sense voltage for Hybrid Microcircuits. Hysteresis HCPL-3700 operating compatibility Each unit contains a light emitting diode (LED), a threshold sensing input buffer IC, and a high gain photon detector to Logic compatible output provide an optocoupler that permits adjustable external 1500 Vdc withstand test voltage threshold levels. The input buffer circuit has a nominal turn on Thresholds guaranteed over temperature threshold of 2.5 mA (I ) and 3.6 volts (V ). The addition of TH+ TH+ Thresholds independent of LED characteristics one or more external attenuation resistors permits the use of this device over a wide range of input voltages and currents. Threshold sensing prior to the LED and detector elements Applications minimizes effects of any variation in optical coupling. Military and space Hysteresis is also provided in the buffer for extra noise High reliability systems immunity and switching stability. Transportation, medical, and life critical systems The buffer circuit is designed with internal clamping diodes to Limit switch sensing protect the circuitry and LED from a wide range of overvoltage Low voltage detector and overcurrent transients while the diode bridge enables easy use with ac voltage input.
