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 protectionrefer AN-213) An on-chip clamp diode capable of handling 800 mA is provided at each output for this purpose In addition the DS3658 incor-porates 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 DS3658 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
