PACKAGE: PLCC44
DESCRIPTION
The L6451 is realized in Multipower BCD Tech-
nology which combines isolated DMOS power
transistors with CMOS and Bipolar circuits on the
same IC. By using mixed technology it has been
possible to optimize the logic circuitry and the
power stage to achieve the best possible perform-
ances.
Intended to be used in ink jet Printer Applications
as 4 to 28 (2 x 14) lines selectable decoder/driver,
the L6451 device driver has the advantages of
low power CMOS inputs and logic, with 28 high
current and high voltage DMOS outputs capable
of sustaining a maximum of 40V.
On system power up the output drivers are locked
out using the chip enable function; two enable in-
puts are available for the different driver banks.
An internal power-on system is implemented in
order to avoid wrong output commutation during
the supply voltage transients.
Using a mask option during manufacturing allows
a different decoding.
Control of the energy delivered to the print head
is made by means of a special circuitry.
All driver outputs are capable of withstanding a
contact discharge of ±8kV with the IC biased.
