DS1603 TRI-STATE ® Dual Receiver General Description The DS16033 is a dual differential TRI-STATE line receiver designed for a broad range of system applications. It features a high input impedance and low input current which reduces the loading effects on a digital transmission line, making it ideal for use in party line systems and general purpose applications like transducer preamplifiers, level translators and comparators. The receivers feature a ± 25 mV input sensitivity specified over a ± 3V common mode range. Input protection diodes are incorporated in series with the collectors of the differential stage. These diodes are useful in applications that have multiple VCC+ supplies or VCC+ supplies that are turned off thus avoiding signal clamping. In addition, TTL compatible strobe and control lines are provide for flexibility in the application. The DS1603 is pin compatible with the DS75107 dual line receiver.
