1. These devices meet or exceed the requirements
of TIA/EIA-485-A, except for the Generator Contention Test (para. 3.4.2) and
the Generator Current Limit (para. 3.4.3). The applied test voltage ranges
are –6 V to 8 V for the SN75ALS176, SN75ALS176A, and SN75ALS176B and –4 V to
8 V for the SN65ALS180.
