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
