| NTE2030 Integrated Circuit High Voltage Segment Driver for Gas Discharge Tubes Description: The NTE2030 is capable of driving 8 segments of a high voltage display tube with a constant output sink current, which can be adjusted by external program resistor, Rp. The program current is half that of output "ON" current. In the "OFF" state the outputs can tolerate more than 80V. The ratio of "ON" output currents is within 10%. Inputs have negative clamp diodes. Active high input logic. The main application of the device is to interface MOS circuits to high- voltage displays.
