DS96172 - RS-485/RS-422 Quad Differential Line Drivers

General Description

The DS96172 and DS96174 are high speed quad differential line drivers designed to meet EIA Standard RS-485.

The devices have TRI-STATE ® outputs and are optimized for balanced multipoint data bus transmission at rates up to 10 Mbps.

Key Features

  • an active high and active low Enable, common to all four drivers. The DS96174 features separate active high Enables for each driver pair. Compatible RS-485 receivers, transceivers, and repeaters are also offered to provide optimum bus performance. The respective device types are DS96173, DS96175, DS96176 AND DS96177. Features n n n n n n n n n Meets EIA Standard RS-485 and RS-422A Monotonic differential output switching Transmission rate to 10 Mbs TRI-STATE outputs Designed for multipoint bus t.

DS96172/DS96174 RS-485/RS-422 Quad Differential Line Drivers June 1998 DS96172/DS96174 RS-485/RS-422 Quad Differential Line Drivers General Description The DS96172 and DS96174 are high speed quad differential line drivers designed to meet EIA Standard RS-485. The devices have TRI-STATE ® outputs and are optimized for balanced multipoint data bus transmission at rates up to 10 Mbps. The drivers have wide positive and negative common mode range for multipoint applications in noisy environments. Positive and negative current-limiting is provided which protects the drivers from line fault conditions over a +12V to −7.0V common mode range. A thermal shutdown feature is also provided and occurs at junction temperature of approximately 160˚C.
