(1)Thes edevices 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 SN75ALS180 and –4 V to 8 V for the SN65ALS180.
The SN65ALS180 and SN75ALS180 differential driver and receiver pairs are integrated circuits designed for bidirectional data communication on multipoint bus-transmission lines. The devices are designed for balanced transmission lines and meet TIA/EIA-422-B, TIA/EIA-485-A, and ITU Recommendation V.11.
The SN65ALS180 and SN75ALS180 combine a 3-state differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, that can be connected together externally to function as a direction control. The driver differential outputs and the receiver differential inputs are connected to separate terminals for greater flexibility and are designed to offer minimum loading to the bus when the driver is disabled or VCC = 0.
These ports feature wide positive and negative common-mode voltage ranges, making the device an excellent choice for party-line applications.
