In addition, the higher current of the SN75112 SN75112 (27 mA) allows data to be transmitted over longer lines. These drivers offer optimum performance when used with the SN55107A SN55107A, SN55108A SN55108A, SN75107A SN75107A, and SN75108A SN75108A line receivers. 4 NC ­ No internal connection These drivers feature independent channels with THE SN75109A SN75109A IS NOT RECOMMENDED FOR NEW DESIGNS 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 6 mA for the '109A, 12 mA for the '110A, and 27 mA for the SN75112 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, IO(off), is specified so that minimum line loading is induced when the driver is used 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.

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 SN55109A and SN55110A SN55110A are characterized for operation over the full military temperature range of ­ 55°C to 125°C. The SN75109A SN75109A, SN75110A SN75110A, and SN75112 SN75112 are characterized for operation from 0°C to 70°C.
