GAS DISCHARGE DISPLAY SEGMENT DRIVERS
DI-232
DI-242
! ! ! !
General Description: The DIONICS DI-232 and DI-242 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 Volts or 125 Volts. These circuits provide for simple interface with display such as Beckman, SP-452, Cherry W4101051 or Dale PD-16A040. Package Layout:
1080 ± 11 435
Features: High Breakdown Voltage: 80V or 125V. High Input Voltage Capability: 40V TTL or MOS Compatible Each Output Programmed By a Single Resistor ! Requires Few Additional Components ! Dielectrically Isolated Integrated Circuits ! DC Restoring Input Diode
