DI-504B
DI-509B
DI-508B
DI-514B
DI-513B
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.
Features:
50V and 80V Level Shift Capability.
MOS and TTL Compatibility
4 -, 6 - and 8-line Versions
Segment and Digit Drivers
Low Power Dissipation
Reliable Dielectric Isolation Process
