The reason that I asked is that I never heard of an ht244. I suspected that it was related to a part with a number like:
74xx244 where the xx indicates the technology used to fabricate the device.
The function of such a device is a tri-state octal buffer. In order to find a datasheet you have to get the part number precisely correct. Sloppy halfway measures just won't do the job. What are your plans for the part?
