Differential Line Transreceiver, SN75117P, Texas Instruments

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 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 input and the receiver output are TTL compatible. 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 stage is similar to a TTL totem-pole output but has 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.
