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
