description

symbol (each driver)

The DS3680 telephone relay driver is a monolithic

integrated circuit designed to interface –48-V

relay systems to TTL or other systems in

telephone applications. It is capable of sourcing

up to 50 mA from standard –52-V battery power.

ToreducetheeffectsofnoiseandIRdropbetween

logic ground and battery ground, these drivers are

designed to operate with a common-mode input

range of ±20 V referenced to battery ground. The

common-mode input voltages for the four drivers

can be different, so a wide range of input elements

can be accommodated. The high-impedance

inputs are compatible with positive TTL and

CMOS levels or negative logic levels. A clamp

network is included in the driver outputs to limit

high-voltage transients generated by the relay coil

during switching. The complementary inputs

ensure that the driver output is off as a fail-safe

condition when either output is open.
