DS1603
TRI-STATE
General Description
The DS16033 is a dual differential TRI-STATE line receiver
designed for a broad range of system applications. It features ahigh input impedance and low input current which reduces theloading effectson adigital transmission line, making itideal for use in party line systems and generalpurpose
applications like transducer preamplifiers, level translators
and comparators.
The receivers feature a
±
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 V
thus avoiding signal clamping. In addition, TTL compatible
strobe andcontrol lines are provide forflexibility in the application.
