Quadruple differential line drivers for motor drives and factory automotive applications
Texas Instruments SN75ALS174A Quadruple Differential Line Drivers are optimised for balanced multipoint bus transmission at rates of up to 20Mbit/s. The device is intended to meet the specifications of ANSI Standards EIA/TIA-422-B and RS-485. The drivers are perfect for party-line applications in noisy settings via wide positive and negative common-mode output voltage ranges. Protection from line fault conditions on the transmission bus line is given through positive and negative-current limiting and thermal shutdown features. Shutdown happens at a junction temperature of approximately 150C. The device operates at temperatures from 0C to 70C.
The device is ideal for use in motor drives, and factory automation and control.
