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 (
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
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
input or both inputs are open the driver will be OFF
