DS3680 Quad Negative Voltage Relay Driver

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 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.

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.

Note 1: ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. 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

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.
