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. DS3680 is capable of sourcing up to 50 mA from standard 52-V battery power.To reduce the effects of noise and IR drop between 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 DS3680 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.

The DS3680 is characterized for operation from 0°C to 70°C.
