This integrated circuit is designed for use in interfacing between TTL-type digital systems and differential data-transmission lines. It is especially useful for party-line (data-bus) applications. This circuit type combines 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 offers 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, using the driver in the normal totem-pole output configuration.
The receiver portion of the SN55116 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 receiver of the SN55116 has an output strobe and a split totem-pole output. The receiver section of the circuit is independent of the driver section, except for the VCC and ground terminals.
The SN55116 is characterized for operation over the full military temperature range of -55°C to 125°C.
