DS3658 Quad High Current Peripheral Driver
DS3658 Quad High Current Peripheral Driver
March 1995
General Description
The DS3658 quad peripheral driver is designed for those
applications where low operating power, high breakdown
voltage, high output current and low output ON voltage are
required. 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 protectionÐrefer AN-213). An onchip clamp diode capable of handling 800 mA is provided at
each output for this purpose. In addition, the DS3658 incorporates circuitry that guarantees glitch-free power up or
down operation and a fail-safe feature which puts the output
in a high impedance state when the input is open.
The molded package is specifically constructed to allow increased 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 Maximum 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 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.
