DI-302
General Description:
LEVEL-SHIFTED GAS DISCHARGE DISPLAY
SEGMENT DRIVER
The DIONICS DI-302 is 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 125V. This eases interfacing
between logic circuitry and display, thus reduces costs.
