Broadcom HCPL-5760#300

These devices are single-channel, hermetic voltage/current threshold-detecting optocouplers. Products are capable of operation and storage over the full temperature range, and are available for purchase as commercial products, with complete MIL-PRF-38534 Class H or Class K testing, or procurement from DLA Standard Microcircuit Drawing (SMD) 5962-89477. All devices are manufactured and tested on MIL-PRF-38534 certified production lines, and Class H and Class K devices are included in the DLA Hybrid Microcircuit Qualified Manufacturers List QML-38534. Each unit contains an LED, a threshold-sensing input buffer IC, and a high-gain photodetector, providing an optocoupler that allows external threshold level adjustment. The nominal turn-on thresholds of the input buffer circuit are 2.5mA (ITH+) and 3.6 volts (VTH+). Adding one or more external attenuation resistors allows the device to be used across a wide range of input voltages and currents. Threshold sensing ahead of the LED and detector elements minimizes the effects of optocoupling variation. Hysteresis is also provided in the buffer to enhance noise immunity and switching stability. The buffer circuit is designed with internal clamp diodes to protect the circuit and LED from various overvoltage and overcurrent transients, while a diode bridge facilitates the use of AC voltage inputs. Note: Normal ESD precautions are recommended when handling and assembling this component to prevent damage and/or performance degradation that may result from electrostatic discharge.
