DI-240A
General Description:
PROG
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.
