This document introduces the general description, features, functions, and connection diagram of the DS1603 TRI-STATE® Dual Receiver. This product is a dual differential TRI-STATE line receiver with high input impedance and low input current, which is ideal for party line systems and general purpose applications such as transducer preamplifiers, level translators, and comparators.
The DS1603 is a dual differential TRI‑STATE line receiver from National Semiconductor. It offers high input impedance, low input current, and a +25 mV input sensitivity over a +3 V common‑mode range, making it suitable for party‑line systems, transducer preamplifiers, level translators and comparators.
The document provides absolute maximum ratings, detailed electrical characteristics, typical application circuits, package dimensions and a life‑support policy notice. It also includes a schematic diagram of one half of the dual circuit and mechanical drawing of the dual‑in‑line package.
