The SN55110A, 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,

SN75107A, and SN75108A line receivers.

NC – No internal connection

These drivers feature independent channels with common voltage supply and ground terminals. The significant

difference between the three 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 12 mA for the ’110A devices, and is 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.

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
