Part Number: SN65LBC180
Other Parts Discussed in Thread: THVD1552

Could you please tell me what is the difference between SN65LBC180DR, SN65LBC180ADR and THVD1552DR?

I hope the infomation of comparison table and if there is some difference at die.

    Hi Kenta,

    They are all different devices - with specifications, but they are pretty similar - however the strongest performance device is the THVD1552.

    Please see a comparison spec table below, Columns 2,3,4 are minimum spec values where applicable, 5,6,7 are typical values where applicable, 8,9,10 are maximum spec'd values.  

    N/A - means this is not applicable to the parameter or device.

    Not Specified means that it could be measured but we didn't specify the value.
