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.
The only way to identify the position or rank of a person in the society is by the color and the quality of the materials used in his clothing. At the time of the Eastern Han dynasty, red became the color that is most respectful because it symbolizes the âfire virtueâ of the Han Dynasty.
