HIGH-VOLTAGE BiMOS III

10-BIT SERIAL-INPUT, LATCHED DRIVERS

Always order by complete part number, e.g., UCN5910A-2 .

The UCN5910x combines a 10-bit CMOS shift register and accompanying

data latches, control circuitry, high-voltage bipolar sourcing outputs with

DMOS active pull-downs. Designed primarily to drive ink-jet and piezoelec-

tric printers, large flat-panel vacuum-fluorescent or ac plasma displays, the

140 V or 150 V and

±50 mA output ratings also allow these devices to be used

in many other peripheral power driver applications. The lower-cost (suffix

“-2”) devices are identical to the basic devices except for output voltage rating.

The CMOS shift register and latches allow direct interfacing with micro-

processor-based systems. With a 5 V logic supply, serial-data input rates are

typically over 5 MHz, with significantly higher speeds obtainable at 12 V.

Use with TTL may require appropriate pull-up resistors to ensure an input logic

high.

A CMOS serial data output enables cascade connections in applications

requiring additional drive lines. Similar devices for up to 60-volt operation are

available in 10, 12, 20, and 32-bit configurations.

The UCN5910A/LW output source drivers are npn Darlingtons capable of

sourcing at least 40 mA. The DMOS active pull-downs are capable of sinking

at least 30 mA. For inter-digit blanking, all of the output drivers can be

disabled and the DMOS sink drivers turned ON by the BLANKING input high.

The UCN5910A and UCN5910A-2 are furnished in a 20-pin dual in-line

plastic package. The surface-mount UCN5910LW and UCN5910LW-2 are

furnished in a wide-body, small-outline plastic package (SOIC) with gull-wing

leads. Copper lead frames, reduced supply current requirements, and lower

output saturation voltages allow all devices to be operated at

±20 mA from all

outputs (50% duty cycle), at ambient temperatures up to +30

°C, or at ±15 mA

to +55

°C.

Caution: CMOS devices have input static

protection but are susceptible to damage when

exposed to extremely high static electrical

charges.

Note that the dual in-line package (designator

‘A’) and small-outline IC package (designator

‘LW’) are electrically identical and share a

common terminal number assignment.
