When the input data is “OFF”, in contrast, “0” is input to the relevant bit
Data Output
When “1” is output to the relevant bit, the corresponding transistor is set to “ON”.
When “0” is output to the relevant bit, in contrast, the corresponding transistor is set to “OFF”.
When the PC is turned on, all output are reset to 0 (OFF).
