1. Notes 2 At output switch point Vo 1 4V Rs OQ with Vcc from 5V to 30V and over the full input common mode range OV to Vcc 1 5V 3 The direction of the input current is out of the IC due to the PNP input stage This current is essentially constant independent of the state of the output so no loading charge exists on the reference or input lines 4 The input common mode voltage of either input signal voltage should not be allowed to go negative by more than 0 3V The upper end of the common mode voltage range is Vcc 1 5V but either or both inputs can go to 30V without damage 5 The response time specified is for a 100mV input step with 5mV overdrive For larger overdrive signals 300ns can be obtained 6 Positive excursions of input voltage may exceed the power supply level As long as the other voltage remains within the common mode range the comparator will provide a proper output state The low input voltage state must not be less than 0 3V or 0 3V below the negative power supply if used 4 3 5 TS391 SUPPLY CURRENT versus INPUT CURRENT versus SUPPLY VOLTAGE SUPPLY VOLTAGE Pa A ee C E 0 4 t Tamb 0 CJ al E ET 25 C4 E Z 0 3 o ee Z E Tamb 70 Cc cr o 0 2 O 2 nee a E 125C J E 20 1 Tamb 125 C R nN 0 10 20 30 40 0 10 20 30 40 SUPPLY VOLTAGE V SUPPLY VOLTAGE V OUTPUT SATURATION2.
