Caution: These CMOS devices have input static
protection (Class 2) but are still susceptible to
damage if exposed to extremely high static
electrical charges.
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.
Three temperature ranges are available for optimum performance
in commercial (suffix S-), industrial (suffix E-), or automotive (suffix
K-) 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).
