An open collector/open drain is a common type of output found on many integrated circuits (IC) . Instead of outputting a signal of a specific voltage or current, the output signal is applied to the base of an internal NPN transistor whose collector is externalized (open) on a pin of the IC.
There were two categories for clothing in the Han Dynasty. They were either the Shenyi (or long coat developed in the Western Han Dynasty) or the Yijin (which makes up the front of the jacket/gown and can be made up of one or two pieces). Itâs been said though that a few people wore the Shenyi during the Eastern Han Dynasty.
Class Differences. Roman dress differed from one class to another. The tunic was worn by plebians (common people), herdsmen and slaves was made from a coarse dark material. The tunic worn by patricians was made from white wool or linen. Magistrates wore the tunic augusticlavia, and senators wore a tunic with broad strips, tunica laticlavia. Military tunics were shorter than those worn by civilians.
