LM311: capture 13V signal

Part Number: LM311
Other Parts Discussed in Thread: LM2903

Hi Team:

 My customer want to use LM311 to capture 13V pulsed quadrature signal for MCU to detect high / low .

 If the ref voltage for LM311 is 6.5V,  does it work with single power supply 15V?  The reason why customer choose LM311 is their Propagation delay time is low as 0.115us,or do we have another recommendation? 

tks !

Here attached the customer waveform when we use LM2903:

 blue one is 13V pulsed quadrature signal(<10Khz) ,yellow one is the square wave signal that MCU need. But too much spurs currently.
