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.

Note 1 “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot

be guaranteed. Except “Operating Temperature Range” they are note meant to imply that

the devices should be operated at these limits. The table of “Electrical Characteristics” pro-

vides conditions for actual device operation.
