74HC164 SOP board Better reliability vs optocouplers —74HC164 SOP registers feature AND gated serial inputs and an asynchronous clear (CLR) input. The gated serial (A and B) inputs permit complete control over incoming data; a low at either input inhibits entry of the new data and resets the first flip flop to the low level at the next clock (CLK) pulse. A high level input enables the other input, which then determines the state of the first flip flop. Data at the serial inputs can be changed while CLK
