DS3669 Quad High Current Peripheral Driver
General Description
The DS3669 is a non-inverting quad peripheral driver similar
to the DS3658 These drivers are designed for those appli-
cations where low operating power high breakdown volt-
age high output current and low output ON voltage are re-
quired A unique input circuit combines TTL compatibility
with high impedance In fact its extreme low input current
allows it to be driven directly by a CMOS device
The outputs are capable of sinking 600 mA each and offer a
70V breakdown However for inductive loads the output
should be clamped to 35V or less to avoid latch-up during
turn off (inductive fly back protection
refer AN-213) An on-
chip clamp diode capable of handling 800 mA is provided at
each output for this purpose In addition the DS3669 incor-
porates circuitry that guarantees glitch-free power up or
down operation
The molded package is specifically constructed to allow in-
creased power dissipation over conventional packages The
four ground pins are directly connected to the device chip
with a special copper lead frame When the quad driver is
soldered into a PC board the power rating of the device
improves significantly

Note 1
``Absolute Maximium Ratings'' are those values beyond which the safety of the device cannot be guaranteed They are not meant to imply that the device
should be operated at these limits The table of ``Electrical Characteristics'' provides conditions for actual device operation
Note 2

a
70 C temperature range and the 4 75V to 5 25V power supply range All typical

Note 3
All currents into device pins are shown as positive all currents out of device pins are shown as negative all voltages are referenced to ground unless
otherwise specified All values shown as max or min are so classified on absolute value basis
Note 4
All sections of this quad circuit may conduct rated current simultaneously however power dissipation averaged over a short interval of time must fall within
specified continuous dissipation ratings
Note 5
For operation over 25 C free-air temperature derate linearly to 1328 mW
