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
protection—refer to AN-213 'SNOA610'). An on-chip
clamp diode capable of handling 800 mA is provided
at each output for this purpose. In addition, the
DS3658 incorporates circuitry that specifies 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 PDIP 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 cooper
lead frame. When the quad driver is soldered into a
PC board, the power rating of the device improves
significantly.
