DI-300 DI-302
LEVEL-SHIFTED GAS DISCHARGE DISPLAY SEGMENT DRIVER
General Description:
The DIONICS DI-300 and DI-302 are designed to drive gas discharge
digital display devices from signals developed in MOS or TTL circuitry.
Each output constitutes a switched constant current sink with a
compliance of up to 100V. This output level can absorb large fluctuation
of supply voltage. The signal is boosted in level by up to 200V (DI-300)
or 125V (DI-302). This eases interfacing between logic circuitry and
display, thus reduces costs.
Features:
Monolithic Silicon Dielectrically Isolated Integrated Circuit
Programmable Constant Current Output
Current Output Range: 0.1 - 2.5mA
200V (DI-300) or 125V (DI-302) Operation
Plastic 18-Pin DIP Package
Level Shifted For Ease Of Use
MOS and TTL Compatibility
Eight-Channel Operation

DI-302 Typical Application
These diagrams depict typical methods for setting output (Cathode) current levels. In some cases, resistor values
should be varied to adjust output current to a proper level for the particular display device used
