OSCILLOSCOPE Fig. 13 Coupled dv/dt - Test Circuit TYPICAL APPLICATIONS 10A, T2L COMPATIBLE, SOLID STATE RELAY Use of the 4N40 for high sensitivity, 5300 V isolation capability, provides this highly reliable solid state relay design. This design is compatible with 74, 74S and 74H series T2L logic systems inputs and 220V AC loads up to 10A. LOAD 47 470 100 +5V "CONTACT" 220 V AC 4N40 "COIL" SC1460 0.1 F 56K 47 IN5060 (4) INDICATER LAMP 25W, LOGIC INDICATOR LAMP DRIVER The high surge capability and non-reactive input characteristics of the 4N40 allow it to directly couple, without buffers, T2L and DTL logic to indicator alarm devices, without danger of introducing noise and logic glitches. 470 +5V 4N40 100 LOGIC INPUT 220 V AC 56K 0.1 F 400V SYMMETRICAL TRANSISTOR COUPLER Use of the high voltage PNP portion of the 4N40 provides a 400V transistor capable of conducting positive and negative signals with current transfer ratios of over 1%. This function is useful in remote instrumentation, high voltage power supplies and test equipment. Care should be taken not to exceed the 40mW power dissipation rating when used at high voltages.
