General Description:
The DIONICS DI-513B and DI-514B series circuits are designed
for interfacing between MOS or TTL circuitry and vacuum
fluorescent display panels. Each section of these devices consists
of a switched constant current level shifter-capable of 50 Volt or
80 Volt- operation and a PNP-NPN driver transistor pair. The
constant current operation of the level shifter stage results in low
power dissipation. Input circuitry is suitable for open drain
PMOS, CMOS, open-collector or standard TTL.
