Description
The ASSR-40xC Series is specifi cally designed for fast switching applications, commonly found in the test and measurement systems. The low C x R and low output off - state leakage current provide higher system throughput and reduce system errors. The dual channel confi guration of ASSR-402C is equiva- lent to 2 Form A Electromechanical Relays (EMR). One channel of the relay consists of an AlGaAs infrared light- emitting diode (LED) input stage optically coupled to a high-voltage output detector circuit. The detector consists of a high-speed photovoltaic diode array and driver circuitry to switch on/off two discrete high volt- age MOSFETs. The relay turns on (contact closes) with a minimum input current of 1mA through the input LED. The relay turns off (contact opens) with an input voltage of 0.8V or less. ASSR-401C is available in 4-pin SO package and ASSR- 402C is available in 8-pin DIP and Gull Wing Surface Mount packages. Their electrical and switching char- acteristics are specifi ed over the temperature range of -40°C to +85°C. Functional Diagram

For qualifi ed device performance over temperature range, it is recommended to operate at IF =5mA. 2. Device is considered as a two terminal device: pins 1, 2, 3 and 4 shorted together and pins 5, 6, 7 and 8 shorted together. 3. The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-outpu t continuous voltage rating. For the continuous voltage rating refer to the IEC/EN/DIN EN 60747-5-2 Insulation Characteristics Table (if app licable), your equipment level safety specifi cation, or Avago Technologies Application Note 1074, “Optocoupler Input-Output Endurance Voltage. ” 4. The PCB design and environmental conditions are taken into consideration when measuring the I O(OFF) performance. 5. During the pulsed R (ON) measurement ( IO duration 30ms), ambient (TA) and case temperature (TC) are equal.
