DABiC-IV, 10-BIT SERIAL-INPUT,

LATCHED SOURCE DRIVERS

The A6809– and A6810– devices combine 10-bit CMOS shift

registers, accompanying data latches and control circuitry with bipolar

sourcing outputs and pnp 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 A6809– and A6810– feature an increased data

input rate (compared with the older UCN/UCQ5810-F) and a con-

trolled output slew rate. The A6809xLW and A6810xLW are identical

except for pinout.

The CMOS shift register and latches allow direct interfacing with

microprocessor-based systems. With a 3.3 V or 5 V logic supply,

typical serial-data input rates are up to 33 MHz.

BLNK 13 BLANKING

A CMOS serial data output permits cascade connections in applica-

tions requiring additional drive lines. Similar devices are avail-able as

the A6811– (12 bits), A6812– (20 bits), and A6818– (32 bits).

The A6809– and A6810– output source drivers are npn Darling-

tons, capable of sourcing up to 40 mA. The controlled output slew rate

reduces electromagnetic noise, which is an important consideration in

systems that include telecommunications and/or microprocessors and

to meet government emissions regulations. For inter-digit blanking, all

output drivers can be disabled and all sink drivers turned on with a

BLANKING input high. The pnp active pull-downs will sink at least

2.5 mA.

All devices are available in two temperature ranges for optimum

performance in commercial (suffix S-) or industrial (suffix E-) applica-

tions. The A6810– is provided in three package styles for through-hole

DIP (suffix -A), surface-mount SOIC (suffix -LW), or minimum-area

surface-mount PLCC (suffix -EP). The A6809– is provided in the

SOIC (suffix -LW) only. Copper lead frames, low logic-power dissi-

pation, and low output-saturation voltages allow all devices to source

25 mA from all outputs continuously over the maximum operating

temperature range.

Caution: These CMOS devices have input

static protection (Class 2) but are still

susceptible to damage if exposed to

extremely high static electrical charges.

Complete part number includes a suffix to identify operating

temperature range (E- or S-) and package type (-A, -EP, or -LW).

Always order by complete part number, e.g., A6810SLW .
