| DIONICS, INC. 65 Rushmore Street Westbury, NY 11590 Phone: (516) 997-7474 Fax: (516) 997-7479 Website: www.dionics-usa.com GAS DISCHARGE DISPLAY SEGMENT DRIVERS DI-230A DI-240A General Description: The DIONICS DI-230A / DI-240A Series circuits are designed to drive gas discharge display devices from signals originating from MOS or TTL circuitry. Each output is a switched, programmable constant current sink with a voltage compliance of 80 or 125 Volts. These circuits provide for simple interfaces with displays such as the Beckman, Burroughs Panaplex, Cherry or equivalents. Features: ! ! ! ! ! ! ! High Breakdown Voltage: 80V or 125V. High Input Voltage Capability: 40V TTL or MOS Compatible All Output Currents Programmed with Single Resistor Requires Few Additional Components Equivalent To DM-8889, MC3491, ITT-505 DC Restoring Input Diode PROG Output Circuit Schematic (Each Section) Input GND Package Layout: Pin Connections 0.900 Out1 18 Out2 17 Out3 16 Out4 15 Out5 14 Out6 13 Out7 12 Out8 11 GND 10 DIONICS INC.
