SN65LVELT22 and MC100LVELT22

Other Parts Discussed in Thread: SN65LVELT22

Hi,

I'd like to ask about SN65LVELT22.

I found "Drop in Compatible to MC100LVELT22" in SN65LVELT22 datasheet.

It seems MC100LVELT22 can input LVCMOS, so I think SN65LVELT22 can input LVCMOS too.

Is my understanding is correct?

Regards,

Yaita

    My customer wants to know if SN65LVELT22 could be used at LVCMOS input.

    Could you follow me please?

    Regards,

    Yes, SN65LVELT22 can be used at LVCMOS input.

     

    It depends on the voltage. We compare LVTTL and LVCOMS as below, LVTTL voltage range is larger than LVCMOS, so LVCMOS can be used in LVTTL input component, but LVTTL maybe can’t be used in LVCMOS input component.

    LVTTL 3.3V voltage:         VOH>=2.4V；VOL<=0.4V；VIH>=2V；VIL<=0.8V

    LVCMOS 3.3V voltage:   VOH>=3.2V；VOL<=0.1V；VIH>=2.0V；VIL<=0.7V

    The SN65LVELT22 input voltage and current is as below, it is ok.
