description

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/SN75113 3-state line driver, and the receiver is similar to the SN55115/SN75115 line receiver.

The SN55116/SN75116 and SN75118 circuits offer all the features of the SN55113/SN75113 driver and the SN55115/SN75115 receiver 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-sink 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- resistor is also provided, which may optionally be used for terminating 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 receiver of the SN55116/SN75116 also has 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 V_CC and ground terminals.

The SN55116 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN75116 and SN75118 are characterized for operation from 0°C to 70°C.
