HIGH-VOLTAGE BiMOS III
10-BIT SERIAL-INPUT, LATCHED DRIVERS
The UCN5910x combines a 10-bit CMOS shift register and accompanying
data latches, control circuitry, high-voltage bipolar sourcing outputs with

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.
