SN65HVD64: SN65HVD64RGTR

Sumangala S

Part Number: SN65HVD64

Hi,

I am testing SN65HVD64RGTR for signal validation of the TXIN & DIR1/2 lines and observing overshoot of ~1.95V (more than 1.8V IO logic) and undershoot of up to -70mV. For this, can I consider the absolute maximum specification of VL+0.3V and -0.3V as the requirements? or it has to be the recommended VIH and VIL levels?

Thanks,

Hi Sumangala,

There shouldn't be too much issue running the inputs with an overshoot as long as its within the abs max spec (after that the esd diodes can turn on and shunt a large amount of current that could lead to device damage).

With that being said - we still recommend that the values be within the rec. operating table in order to reduce stress onto the part.

Please let me know if you have an other questions!

Best,

Parker Dodson
