DS3680 Datasheet | National Semiconductor

Description The DS3680 is a quad high voltage negative relay driver designed to operate over wide ranges of supply voltage mon-mode voltage and ambient temperature with 50 m A 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 mon-mode range ( g 20V referenced to negative supply ground) Each driver has a mon-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 m A) these drivers are patible with TTL LS and CMOS logic Differential inputs permit either inverting or non-inverting operation 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 Features Y Y Y Y Y Y Y b 10V to b 60V operation Quad 50 m A sink capability TTL LS S or voltage parator input High input mon-mode voltage range Very low input current Fail-safe disconnect feature Built-in output clamp diode Connection Diagram Dual-In-Line Package Logic Diagram TL F 5821 - 1 Top View Order Number DS3680J DS3680M or DS3680N See NS Package Number J14A M14A N14A TL F 5821 - 2 Truth Table Differential Inputs VID t 2V VID s 0 8V Open Outputs On Off Off C1995 National Semiconductor Corporation TL F 5821 RRD-B30M105 Printed in U S A Absolute Maximum Ratings (Note 1) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage (GND to VEEb and Any Pin) Positive...
