This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines. 3) 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. 4) Positive voltage excursions of one input may exceed the power supply level. As long as the other input voltage remains within the common-mode range, the comparator will provide an appropriate output state. The low input voltage state must not be less than -0.3V (or 0.3V below the negative power supply, if used). 5) The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals, 300ns can be obtained 3/7 TSM109/A Electrical Characteristics COMPARATOR (comparator with inverting input connected to the internal Vref)) VCC+ = +5V, VCC-= GND, Tamb = +25°C (unless otherwise specified) TSM109 Symbo l Parameter Unit Min.
