1 / 6 page  TLF5821 March 1995 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 switch- ing 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 be- tween logic ground and negative supply ground in many ap- plications these drivers are designed to operate with a high common-mode range (g20V 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 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 aIN input or both inputs are open the driver will be OFF Features Y b 10V to b60V operation Y Quad 50 mA sink capability Y TTLLSCOMS or voltage comparator input Y High input common-mode voltage range Y Very low input current Y Fail-safe disconnect feature Y Built-in output clamp diode Connection Diagram Dual-In-Line Package TLF5821 – 1 Top View Order Number DS3680J DS3680M or DS3680N See NS Package Number J14A M14A N14A Logic Diagram TLF5821 – 2 Truth Table Differential Inputs Outputs VID t 2V On VID s 08V Off Open Off C1995 National Semiconductor Corporation RRD-B30M105Printed in U S A |
