SN751178N DUAL DIFFERENTIAL DRIVERS/RECEIVERS

The SN751177 and SN751178 dual differential drivers and receivers are monolithic integrated circuits that are designed for balanced multipoint bus transmission at rates up to 10 Mbit/s. They are designed to improve the performance of full-duplex data communications over long bus lines and meet ANSI .

SN751177, SN751178 DUAL DIFFERENTIAL DRIVERS AND RECEIVERS SLLS059D FEBRUARY 1990 REVISED MAY 1999 D Meet or Exceed the Requirements of ANSI Standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.10 and V.11 D Designed for Multipoint Bus Transmission on Long Bus Lines in Noise Environments D Driver Positive- and Negative-Current Limiting D Thermal Shutdown Protection D Driver 3-State Outputs D Receiver Common-Mode Input Voltage Range of 12 V to 12 V D .

SN751178N Features

* high input impedance of at least 12 kΩ, an input sensitivity of ±200 mV over a common-mode input voltage range of

* 12 V to 12 V, and typical input hysteresis of 50 mV. Fail-safe design ensures that if the receiver inputs are open, the receiver outputs always will be high. The SN751177 and S
