Overview

5812-F UCN5812EPF SERIAL DATA OUT LOGIC SUPPLY LOAD SUPPLY OUT20 SERIAL DATA IN OUT19 OUT 1 BiMOS II 20-BIT SERIAL-INPUT, LATCHED SOURCE DRIVERS WITH ACTIVE-DMOS PULL-DOWNS The UCN5812AF/EPF combine a 20-bit CMOS shift register, data latches, and control circuitry with high-voltage bipolar source drivers and active DMOS pull-downs for reduced supply current requirements.
Although designed primarily for vacuum-fluorescent displays, the high-voltage, highcurrent outputs also allow them to be used in other peripheral power driver applications.
They are improved versions of the original UCN5812A/EP.
