LEVEL-SHIFTED VACUUM FLUORESCENT DISPLAY DRIVERS
DI-512BR*
DI-513BR
DI-514BR
(* Also directly applicable as gas discharge display digit driver. Pin for pin replacement for SPRAGUE UDN6184A)
General Description:
The DIONICS DI-512BR, DI-513BR and DI-514BR circuits are designed for interfacing between MOS or TTL
logic circuitry and vacuum fluorescent display panels. Each section of these devices consists of a switched
constant current level shifter (capable of 50 Volt, 80 Volt or 110 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.
