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.
