Part Number: TIPD144 I use the same circuit as figure, just change TLV3201 to LM393 . The problem is when I input a sine wave between VH and VL, the Multisim simulate output result is a sine wave. Shouldn't it be a low level signal?
Hello Pin,
Because they share common input and reference dividers, they will affect each other depending on the state of each output. This becomes quite complex.
First, I would recommend reading the following Appnotes to get acquainted with the hysteresis…
Hello Anthony,
There may have been a few typos in the videos. The proper TIPD#'s are TIPD105 and TIPD144. Links below:

Hello Vladimir,
I recommend reading TIPD144 Comparator with Hysteresis Reference Design to learn how to add hysteresis to a comparator. This reference design describes the theory and design procedure on how to add inverting hysteresis to a comparator…
Hi Leonard,
If you need information about applying hysteresis to comparators see TIPD144 in the TI Designs series:

Hi Stephen,
The maximum suggested hysteresis is ±130mV, as explained in Section 7.3.3 in the datasheet Apps section.
You may be able to scale-down the incoming voltages to multiply the effective hysteresis.
Also note that the LMP7300 was designed for…
Hi Vishal,
What you've noticed is common in comparator applications. Basically, if noise is present on the static input or the triangle wave input then as the triangle wave passes through the static input, the comparator output may transition several…
Hello Anoop,
We don't information about operating the TL3016 with +/-3.3 V supplies, but some safe assumptions can be made based on the +/-5 V supply operating information. The TL3016 will function well with +/-3.3 V supplies, but do expect the ac…
