i think many of you worked with ht12e in your remote controls

i have a doubt with ht12e tx here i powered up ht12e the vt is made low absolutely zero

the data pins read 0.25v each with respect to ground and data out reads 2.5v and changing to 4v some times keeps changing

Check the Datasheet.

The data output is a pulse train and cannot be measured as a 'DC voltage' due to the on-off switching of the data bits.
