Example of printing using a strobe pulse

This offers the advantage that the common line (large

current) of the heat element does not need to be

switched.

The BA823 has the internal configuration shown in the

logic diagram, with the following three input pins: clock

C, data DI, and strobe S. Data input is synchronized to

the clock, with data being read serially at the rising

edge. The content of the set shift register appears at

in Figure 8, depending on the strobe input, with that

pulse width being the same as that of the strobe input.

in cascade format, and when the output for the last

stage of the shift register appears, is connected to the

latches and power switch are used in common, the out-

put pins can be increased by eight bits each.
