DUAL LINE DRIVERS

2–2

POST OFFICE BOX 655303

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.
