HCPL-3700
DESCRIPTION
The HCPL-3700 voltage/current threshold detection optocoupler consists of an AlGaAs LED connected to a threshold sensing input buffer IC which are optically coupled to a high gain darlington output. The input buffer chip is capable of controlling threshold levels over a wide range of input voltages with a single resistor. The output is TTL and CMOS compatible.

NOTES
1. Derate linearly above 70C free-air temperature at a rate of 1.8 mW/C. 2. Derate linearly above 70C free-air temperature at a rate of 2.5 mW/C. 3. Derate linearly above 70C free-air temperature at a rate of 0.6 mA/C. 4. Derate linearly above 70C free-air temperature at a rate of 1.9 mW/C. 5. Logic low output level at pin 6 occurs when VINVTH+ and when VIN>VTH- once VIN exceeds VTH+. Logic high output level at pin 6 occurs when VINVTH- and when VIN2.0 V). Common mode transient immunity in logic low level is the maximum tolerable (negative) dVcm/dt on the trailing edge of the common mode pulse signal, VCM, to assure that the output will remain in a logic low state (i.e., VO<0.8 V). (Refer to Fig.10) 8. In applications where dVcm/dt may exceed 50,000 V/s (Such as static discharge), a series resistor, RCC, should be included to protect the detector chip from destructive surge currents. The recommended value for RCC is 240 V per volt of allowable drop in VCC (between pin 8 and VCC) with a minimum value of 240 . 9. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are shorted together. 10. The 2500 VRMS/1 min. capability is validated by a 3.0 kVRMS/1 sec. dielectric voltage withstand test. 11. AC voltage is instantaneous voltage for VTH+ & VTH-. 12. All typicals at TA = 25C, VCC = 5 V unless otherwise specified.
