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.
A Roman could tell how important or wealthy a person was from their toga. Free Roman men wore the toga instead of a cloak. It was originally an Etruscan garment worn in earlier times by both men and women of all classes. The toga was made from white wool or white Egyptian linen.
