LEVEL-SHIFTED GAS DISCHARGE DISPLAY DIGIT DRIVERS
DI-500B
DI-502B
General Description:
The DIONICS DI-500B and DI-502B circuits are designed for
interfacing between MOS or TTL circuitry and gas discharge
display panels. Each section of these devices is made up of a
switched constant current level shifter-capable of high voltage
operation-and a pnp-npn driver transistor pair. The constant
current operation of the level shifter stage results in low power
dissipation. Input circuitry is suitable for open drain PMOS,
CMOS, open-collector or standard TTL.
