(refer to fig. 9) 7. common mode transient immunity in logic high level is the maximum tolerable (positive) dv cm /dt on the leading edge of the common mode pulse signal v cm , to assure that the output will remain in a logic high state (i.e., v o > 2.0 v). common mode transient immunity in logic low level is the maximum tolerable (negative) dv cm /dt on the trailing edge of the common mode pulse signal, v cm , to assure that the output will remain in a logic low state (i.e., v o < 0.8 v). refer to fig. 10. 8. in applications where dv cm /dt may exceed 50,000 v/? (such as static discharge), a series resistor, r cc , should be included to protect the detector chip from destructive surge currents. the recommended value for r cc is 240v per volt of allowable drop in v cc (between pin 8 and v cc ) 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 v rms /1 min. capability is validated by a 3.0 kv rms /1 sec. dielectric voltage withstand test. 11. ac voltage is instantaneous voltage for v th+ & v th- . 12. all typicals at t a = 25?, v cc = 5v unless otherwise speci?d. symbol ac characteristics test conditions min. typ. max. unit t phl propagation delay time (to output low level) r l = 4.7k ? , c l = 30pf (6) 6.0 15 ? t plh propagation delay time (to output high level) r l = 4.7k ? , c l = 30pf (6) 25.0 40 ? t r output rise time (10?0%) r l = 4.7k ? , c l = 30pf 45 ? t f output fall time (90?0%) r l = 4.7k ? , c l = 30pf 0.5 ? |cm h | common mode transient immunity (at output high level) i in = 0 ma, r l = 4.7k ? , v o min = 2.0 v, v cm = 1400v (7)(8) 4000 v/? |cm l | common mode transient immunity (at output low level) i n = 3.11ma, r l = 4.7k ? , v o max = 0.8v, v cm = 140v (7)(8) 600 v/? symbol characteristics test conditions min. typ. max. unit v iso withstand insulation voltage relative humidity < 50%, t a = 25?, t = 1 min, i i-o 2?
