SN75ALS176P Datasheet | Texas Instruments

description The SN65ALS176 and SN75ALS176 series differential bus transceivers are designed for bidirectional data munication on multipoint bus transmission lines. They are designed for balanced transmission lines and meet TIA/EIA-422-B, TIA/EIA-485-A, and ITU Remendations V.11 and X.27. The SN65ALS176 and SN75ALS176 series bine 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 internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or VCC = 0. This port features wide positive and negative mon-mode voltage ranges, making the device suitable for party-line applications. The SN65ALS176 is characterized for operation from - 40°C to 85°C. The SN75ALS176 series is characterized for operation from 0°C to 70°C. Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. † 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. PRODUCTION DATA information is current as of publication date.
