The Texas Instruments DS3680DR is a monolithic integrated circuit designed as a telephone relay driver. It is specifically engineered to interface -48V relay systems with TTL or CMOS logic levels in telecommunication applications.
This device is capable of sourcing up to 50 mA from a standard -52V battery power supply. It features a high common-mode input voltage range of ±20V referenced to battery ground, accommodating various input elements and reducing noise effects. The inputs are compatible with positive TTL and CMOS levels or negative logic levels, offering flexibility in system design.
The DS3680DR includes a built-in output clamp diode to limit high-voltage transients generated by the relay coil during switching. A fail-safe disconnect feature ensures the driver output is off when either output is open. The device is characterized for operation in an ambient temperature range of 0°C to 70°C and is available in a 14-SOIC surface mount package.
This integrated circuit is a direct replacement for National DS3680 and Fairchild mA3680. Its robust design makes it suitable for various telecom infrastructure and equipment applications.
The DS3680DR operates from 0°C to 70°C.
The DS3680DR can source up to 100 mA with a resistive load and 50 mA with an inductive load.
The DS3680DR is available in a 14-SOIC package.
The input voltage range with respect to battery ground is -70V to 20V.
