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
