SN75110A, and SN75112 dual line drivers have
improved output current regulation with supply
voltage and temperature variations. In addition,
the higher current of the SN75112 (27 mA) allows
data to be transmitted over longer lines. These
drivers offer optimum performance when used
with the SN55107A, SN55108A, SN75107A, and
SN75108A line receivers.

These drivers feature independent channels with

The significant difference between the three
THE SN75109A IS NOT
RECOMMENDED FOR NEW DESIGNS
drivers is in the output current specification. The driver circuits feature a constant output current that is switched
to either of two output terminals by the appropriate logic levels at the input terminals. The output current can
be switched off (inhibited) by low logic levels on the enable inputs. The output current is nominally 6 mA for the
’109A, 12 mA for the ’110A, and 27 mA for the SN75112.
The enable/inhibit feature is provided so the circuits can be used in party-line or data-bus applications. A strobe
or inhibitor (enable D), common to both drivers, is included for increased driver-logic versatility. The output
current in the inhibited mode, I
, is specified so that minimum line loading is induced when the driver is used
O(off)
in a party-line system with other drivers. The output impedance of the driver in the inhibited mode is very high.
The output impedance of a transistor is biased to cutoff.

description (continued)
The driver outputs have a common-mode voltage range of –3 V to 10 V, allowing common-mode voltage on
the line without affecting driver performance.
All inputs are diode clamped and are designed to satisfy TTL-system requirements. The inputs are tested at
2 V for high-logic-level input conditions and 0.8 V for low-logic-level input conditions. These tests ensure
400-mV noise margin when interfaced with TTL Series 54/74.
The SN55109A and SN55110A are characterized for operation over the full military temperature range of – 55°C
to 125°C. The SN75109A, SN75110A, and SN75112 are characterized for operation from 0°C to 70°C.

APPLICATION INFORMATION
using the SN75112 as a CCITT recommended V.35 line driver
The SN75112 dual line driver, the SN75107A dual line receiver, and some external resistors can be used to
implement the data interchange circuit of CCITT recommendation V.35 (1976) modem specification. The circuit
of one channel is shown in Figure 1 and meets the requirement of the interface as specified by Appendix 11 of
CCITT V.35 and summarized in Table 1 (V.35 has been replaced by ITU V.11).
