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 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-Ω 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

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.
