A low level on the data entry and an output from each of the eight clear input overrides all other inputs and clears the stages. Data is entered serially through one of two register asynchronously, forcing all Q outputs low. inputs (A or B), either of these inputs can be used All inputs are equipped with protection circuits as an active high enable for data entry through the against static discharge and transient excess other input. An unused input must be high, or both voltage. inputs connected together. Each low-to-high PIN CONNECTION AND IEC LOGIC SYMBOLS June 2003 1/13
