SN75ALS176ADR
RS-485/422A差分总线收发器
The SN65ALS176 and SN75ALS176 series differential bus transceivers are designed for bidirectional data communication on multipoint bus transmission lines. They are designed for balanced transmission lines and meet A/EIA-422-B, TIA/EIA-485-A, and ITU Recommendations V.11 and X.27.
The SN65ALS176 and SN75ALS176 series 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 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 common-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. View datasheet View product folder
