SN65LBC174

SN65LBC174, SN75LBC174 QUADRUPLE LOW-POWER DIFFERENTIAL LINE DRIVERS SLLS162D – JULY 1993 – REVISED SEPTEMBER 2003 D Meets or Exceeds the Standard EIA-485 D Designed for High-Speed Multipoint Transmission on Long Bus Lines in Noisy Environments D Supports Data Rates up to and Exceeding Ten Million Transfers Per Second D Common-Mode Output Voltage Range of – 7 V to 12 V D Positive- and Negative-Current Limiting D Low Power Consumption . . . 1.5 mA Max (Output Disabled) D Functionally Interchangeable With SN75174 description The SN65LBC174 and SN75LBC174 are monolithic, quadruple, differential line drivers with 3-state outputs. Both devices are designed to meet the requirements of the Electronics Industry Association Standard EIA-485. These devices are optimized for balanced multipoint bus transmission at data rates up to and exceeding 10 million bits per second. Each driver features wide positive and negative common-mode output voltage ranges, current limiting, and thermalshutdown protection, making it suitable for party-line applications in noisy environments. Both devices are designed using LinBiCMOS, facilitating ultralow power consumption and inherent robustness. Both the SN65LBC174 and SN75LBC174 provide positive- and negative-current limiting and thermal shutdown for protection from line fault conditions on the transmission bus line. These devices offer optimum performance when used with the SN75LBC173 or SN75LBC175 quadruple line receivers. The SN65LBC174 and SN75LBC...
