DS3656 Quad Peripheral Driver General Description sients and reverse battery connection. In this type of environment an external 100X resistor must be connected in series with the VCC line. The DS3656 is a quad peripheral driver designed for use in automotive applications. Logically it is an open collector NAND function with all inputs compatible with 74LS and CMOS series products. An enable input is provided that is common to each driver. When taken to a logic zero level all outputs will turn off. Also, overvoltage is detected. The DS3656 has features associated with the output structure that make it highly versatile to many applications. Each output is capable of 600 mA sink currents and offers 65V standoff voltage in non-inductive applications. A clamp network capable of handling 800 mA is incorporated in each output which eliminates the need of an external network to quench the high voltage backswing caused when switching inductive loads up to 30V (reference AN-213). The DS3656 is intended to operate from a 12V automotive battery. Internal to the device is its own voltage regulator which permits the device to operate during the wide voltage variation seen in many automotive applications. An overvoltage-protection circuit is incorporated that will cause the outputs to turn off when the supply exceeds 30V. The circuit is designed to withstand worst case fault conditions that occur in automotive applications, such as high voltage tran- 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 copper PC board the power rating of the device will significantly improve.
