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.
Features:
D Versatile Circuits for a Wide Range of Display Applications
D High Breakdown Voltages
D Low Power Dissipation

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.
