description
The SN75ALS1177 and SN75ALS1178 dual
differential drivers and receivers are monolithic
integrated circuits designed for bidirectional data
communication on multipoint bus transmission
lines. They are designed for balanced transmis-
sion lines and meet standards EIA/TIA-422-B,
RS-485, and CCITT Recommendation V.11.
The SN75ALS1177 combines dual 3-state differential line drivers and dual 3-state differential input line
receivers, both of which operate from a single 5-V power supply. The drivers and receivers have active-high
and active-low enables, respectively, which can be externally connected together to function as direction
control. The SN75ALS1178 drivers each have an individual active-high enable. Fail-safe design ensures that
when the receiver inputs are open, the receiver outputs are always high.
The SN75ALS1177 and SN75ALS1178 are characterized for operation from 0
°
C to 70
°
C.
