NSC DS1603J/883 Tri-state dual receiver Datasheet

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.

Note 2: “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 devices should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation.
Note 3: Unless otherwise specified min/max limits apply across the −55˚C to +125˚C temperature range for the DS1603 and across the 0˚C to +70˚C range for the
DS3603. All typical values are for TA = 25˚C and VCC = 5V.
