Caution: Allegro CMOS devices have input static

protection but are susceptible to damage when

exposed to extremely high static electrical

charges.

Note that the UCN5812AF (dual in-line package)

and UCN5812EPF (PLCC package) are electri-

cally identical and share a common terminal

number assignment.

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, high-

current outputs also allow them to be used in other peripheral power driver

applications. They are improved versions of the original UCN5812A/EP.

microprocessor-based systems. With a 5 V supply, they will operate to at

least 3.3 MHz. At 12 V, higher speeds are possible. Especially useful for

inter-digit blanking, the BLANKING input disables the output source drives

and turns on the DMOS sink drivers. Use with TTL may require the use of

appropriate pull-up resistors to ensure an input logic high.

furnished in 28-lead plastic chip carrier (quad pack) with 0.050"(1.22 mm)

centers. Copper lead-frames, reduced supply current requirements and lower

output saturation voltages, allow continuous operation, with all outputs

sourcing 25 mA, of the UCN5812AF over the operating temperature range,

and the UCN5812EPF up to +75°C. All devices are also available for opera-

tion between -40°C and +85°C. To order, change the prefix from ‘UCN’ to

‘UCQ’.
