NTE2025
Integrated Circuit
Quad HV Driver for Gas−Discharge Display
Description:
Designed for interfacing between MOS, or other low−voltage circuitry, and the anode of gas discharge
display panels, these monolithic high−voltage bipolar integrated circuits dramatically reduce the number of discrete components required. The NTE2025 is used with multiplexed gas discharge display
panels. The driver contains appropriate level shifting, signal amplification, output off state voltage
bias, and 70mA output current sourcing for the sequential addressing of display panel anodes. The
inputs inmclude pull−down resistors for direct connection to open drain PMOS logic.
