Row (example)
The processor sends a signal to the column circuit, causing the output of the UNL-2803 to toggle. When point 'A'
drops low, the TIP107 transistor conducts and point 'B' changes to a high state. At the same time the processor
drives the input of the 74LS74 low, causing a high at output 'F'. A high state at the base of TIP102 causes the
transistor to conduct, bringing the row circuit to ground and tuming the lamp On.
The processor changes the input of the 74LS74 to a high state to tum the lamp Off.
In overcurrent conditions the lamp is shut Off through the comparator. If the voltage at the negative input of the
LM339 rises above 1.4V the output changes to a low, which is fed back to the 74LS74 and shuts the row circuit Off.
