DABiC-IV, 20-BIT SERIAL-INPUT,  
LATCHED SOURCE DRIVER  
The A6812– devices combine a 20-bit CMOS shift register,  
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 A6812– features an increased data input rate (com-  
pared with the older UCN/UCQ5812-F) and a controlled output slew  
rate.

The CMOS shift register and latches allow direct interfacing with  
microprocessor-based systems. With a 3.3 V or 5 V logic supply, they  
will operate to at least 10 MHz.

A CMOS serial data output permits cascade connections in applica-  
tions requiring additional drive lines. Similar devices are available as  
the A6809– and A6810– (10 bits), A6811– (12 bits), and A6818– (32  
bits).

The A6812– output source drivers are npn Darlingtons, capable of  
sourcing up to 40 mA. The controlled output slew rate reduces electro-  
magnetic 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 BLANK-  
ING input high. The pnp active pull-downs will sink at least 2.5 mA.

Two temperature ranges are available for optimum performance in  
commercial (suffix S-) or industrial (suffix E-) applications. Package  
styles are provided for through-hole DIP (suffix -A), surface-mount  
SOIC (suffix -LW), or minimum-area surface-mount PLCC (suffix  
-EP). Copper lead frames, low logic-power dissipation, and low  
output-saturation voltages allow these drivers to source 25 mA from all  
outputs continuously to more than +43°C (suffix -LW), +61°C (suffix  
-EP), or +77°C (suffix -A).

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., A6812SLW .
