DS3680 Quad Negative Voltage Relay Driver General Description The DS3680 is a quad high voltage negative relay driver designed to operate over wide ranges of supply voltage, common-mode voltage, and ambient temperature, with 50 mA sink capability. These drivers are intended for switching the ground end of loads which are directly connected to the negative supply, such as in telephone relay systems. Since there may be considerable noise and IR drop between logic ground and negative supply ground in many applications, these drivers are designed to operate with a high common-mode range ( g 20V referenced to negative supply ground). Each driver has a common-mode range separate from the other drivers in the package, which pemits input signals from more than one element of the system. With low differential input current requirements (typically 100 mA), these drivers are compatible with TTL, LS and CMOS logic. Differential inputs permit either inverting or non-inverting operation. Connection Diagram The driver outputs incorporate transient suppression clamp networks, which eliminate the need for external networks when used in applications of switching inductive loads. A fail-safe feature is incorporated to insure that, if the a IN input or both inputs are open, the driver will be OFF.

Except for ‘‘Operating Temperature Range’’, 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 2: Unless otherwise specified, the min/max limits of the table of ‘‘Electrical Characteristics’’ apply within the range of the table of ‘‘Operating Conditions’’. All typical values are given for VEEb e 52V, and TA e 25§ C. Note 3: All current into device pins shown as positive, out of the device as negative. All voltages are referenced to ground unless otherwise noted. 2 Schematic Diagrams TL/F/5821 – 3 TL/F/5821 – 4 Physical Dimensions inches (millimeter) Ceramic Dual-In-Line Package (J) Order Number DS3680J NS Package Number J14A 3 Physical Dimensions inches (millimeters) (Continued) SO Package (M) Order Number DS3680M NS Package Number M14A Molded Dual-In-Line Package (N) Order Number DS3680N NS Package Number N14A 4 5 DS3680 Quad Negative Voltage Relay Driver LIFE SUPPORT POLICY NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF NATIONAL SEMICONDUCTOR CORPORATION.
