2003 The driver chip is a high voltage, high current Darlington display, consisting of seven silicon NPN Darlington tubes. Each pair of Darlington is connected in series with a 2.7K base resistor, which can be directly connected to TTL and CMOS circuits at 5V operating voltage, and can directly process data that previously required standard logic buffers to process.
The working voltage is high, the working current is large, the filling current can reach 500mA, and it can withstand 50V voltage in the off state, and the output can also run in parallel with high load current.
