These integrated circuits are designed for use in interfacing between TTL-type digital systems and differential data-transmission lines. They are especially useful for party-line (data-bus) applications. Each of these circuit types combine in one package a 3-state differential line driver and a differential-input line receiver, both of which operate from a single 5-V power supply. The driver inputs and the receiver outputs are TTL compatible. The driver employed is similar to the SN55113 and SN75113 3-state line drivers, and the receiver is similar to the SN55115 and SN75115 line receivers. The SN55116, SN75116, and SN75118 offer all the features of the SN55113 and SN75113 drivers and the SN55115 and SN75115 receivers combined. The driver performs the dual input AND and NAND functions when enabled or presents a high impedance to the load when in the disabled state. The driver output stages are similar to TTL totem-pole outputs, but have the current-sinking portion separated from the current-sourcing portion and both are brought out to adjacent package terminals. This feature allows the user the option of using the driver in the open-collector output configuration, or, by connecting the adjacent source and sink terminals together, of using the driver in the normal totem-pole output configuration. The receiver portion of the SN55116, SN75116, and SN75118 features a differential-input circuit having a common-mode voltage range of ±15 V. An internal 130- equivalent resistor also is provided, which optionally can be used to terminate the transmission line. A frequency-response control terminal allows the user to reduce the speed of the receiver or to improve differential noise immunity. The receivers of the SN55116 and SN75116 have an output strobe and a split totem-pole output. The receiver of the SN75118 has an output-enable for the 3-state split totem-pole output. The receiver section of either circuit is independent of the driver section except for the VCC and ground terminals. The SN75117 and SN75119 provide the basic driver and receiver functions of the SN55116, SN75116, and SN75118, but use a package that is only half as large. The SN75117 and SN75119 are intended primarily for party-line or bus-organized systems because the driver outputs are internally connected to the receiver inputs. The driver has a single data input and a single enable input. The SN75117 receiver has an output strobe, while the SN75119 receiver has a 3-state output enable. However, these devices do not provide output connection options, line-termination resistors, or receiver frequency-response controls.The SN55116 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN75116, SN75117, SN75118, and SN75119 are characterized for operation from 0°C to 70°C. \n

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 Standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.10 and V.11. The SN751177 and SN751178 driver outputs provide limiting for both positive and negative currents and thermal-shutdown protection from line-fault conditions on the transmission bus line. The receiver features high input impedance of at least 12k , 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 SN751178 are characterized for operation from -20°C to 85°C.
