DS75115/DS9615 Dual Differential Line Receiver General Description Features The DS75115/DS9615 is a dual differential line receiver designed to sense differential signals from data transmission lines. Designed for operation over military and commercial temperature ranges, the DS75115/DS9615 can typically receive g 500 mV differential data with g 15V common-mode noise. Outputs are open-collector and give TTL compatible signals which are a function of the polarity of the differential input signal. Active output pull-ups are also available, offering the option of an active TTL pull-up through an external connection. Response time may be controlled with the use of an external capacitor. Each channel may be independently controlled and optional input termination resistors are also available. Y Y Y Y Y Y Y Y Single 5V supply High common-mode voltage range Each channel individually strobed Independent response time control Uncommitted collector or active pull-up option TTL compatible output Optional 130X termination resistors Direct replacement for 9615 Connection Diagram Function Table Dual-In-Line Package Strobe Diff.
