TLV3501: TLV3501: pluse input . output oscillation

Hi Sir:

    I use the high-speed Comp  TLV3501. But when I use the DC single input，it can the Vpp=20mV the Device can output the waveform normal。But when I use a pulse single the Vpp must be over 200mV。 Otherwise, the output like oscillation。 And I Add a Feedback capacitance form output to input。But the effect is not ideal
