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.
