C OPERATION
Always order by complete part number, e.g., UCQ5810AF .
The UCQ5810AF and UCQ5810LWF combine a 10-bit 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
UCQ5810AF/LWF feature reduced supply requirements (active DMOS pull-
downs) and lower saturation voltages when compared with the original
UCQ5810A.
The CMOS shift register and latches allow direct interfacing with
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.
A CMOS serial data output enables cascade connections in applications
requiring additional drive lines. Similar devices are available as the
UCQ5811A (12 bits), UCQ5812AF/EPF (20 bits), and UCQ5818AF/EPF (32
bits).
The UCQ5810AF/LWF output source drivers are npn Darlingtons
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 UCQ5810AF is furnished in an 18-pin dual in-line plastic package.
The UCQ5810LWF 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.
