TLV1701: propagation delay versus input overdrive

Part Number: TLV1701
Other Parts Discussed in Thread: TLV3201, TLV7011

Dear Experts,

My customer is evaluating this product and wants to know more about propagation delay versus input overdrive. 

Specifically, in the typical curve (figure 8), the plot starts from ~100mV. Do we have any data at 1mV and 10mV that we can provide to the customer?

Thank you

    Unfortunately, that is how the device was characterized.  I looked for any simulation data that could show the slowing of prop delay with lower overdrive, but that did not turn up any useful information.  This device is not a tremendously fast device.  May I ask what the use case is?  It is safe to assume that the prop delay will start to increase once the OD drops below 10mV.  If the application needs faster response with minimal OD and the use case can accommodate a 5V comparator, the response will be faster if they use a device such as the TLV3201 or TLV7011.  These are push pull output stages and will provide more symmetrical output response for output rise and fall times.


  • Hi Chuck,

    Thank you for your comments, which I’ve passed on to our customer.

    The application is over-current protection in a power supply unit. Initially the requirement for the comparator was high voltage output and fast response at low overdrive conditions. It is for upgrading an existing design so I’m not sure how much flexibility there is to tweak the topology. But I’ll let you know if there are further questions.

    Regards, Guang
