LMV321A: hysteresis comparison circuit

Part Number: LMV321A
Other Parts Discussed in Thread: LMV321

Hi team


I use LMV321 to design a hysteresis comparison circuit. According to my calculation of resistance value, when the output level is high, V1 should be greater than 4.2V, when the output level is low, V1 should be less than 4V.However, the result of transient simulation in pspice for TI is out of expectation.

Could you please help me analyze the reason and provide solution?


Best Regards
