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
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.
