Caution: CMOS devices have input static
protection but are susceptible to damage when
exposed to extremely high static electrical
charges.
Note that the UCN5810AF (dual in-line package)
and UCN5810LWF (small-outline IC package) are
electrically identical and share a common pin
number assignment.

CMOS shift register and accompanying data latches, control circuitry, bipolar
sourcing outputs with DMOS active pull-downs. Designed primarily to drive
vacuum-fluorescent displays, the 60 V and -40 mA output ratings also allow
these devices to be used in many other peripheral power driver applications.
The UCN5810AF/EPF/LWF feature reduced supply requirements (active
DMOS pull-downs) and lower saturation voltages when compared with the
original UCN5810A.
microprocessor-based systems. With a 5 V supply, they will operate to at
least 3.3 MHz. At 12 V, higher speeds are possible. Use with TTL may
require appropriate pull-up resistors to ensure an input logic high.
requiring additional drive lines. Similar devices are available as the
UCN5811A (12 bits), UCN5812AF/EPF (20 bits), and UCN5818AF/EPF (32
bits).
capable of sourcing up to 40 mA. The DMOS active pull-downs are capable
of sinking up to 15 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 UCN5810EPF is furnished in a 20-lead plastic chip carrier. The
UCN5810LWF is 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 source
25 mA from all outputs continuously, over the entire operating temperature
range. All devices are also available for operation between -40°C and +85°C.
To order, change the prefix from ‘UCN’ to ‘UCQ’.
