SN55LBC174J General Description

The SN55LBC174 is composed of monolithic quadruple differential line drivers with 3-state outputs. This device is designed to meet the requirements of the Electronics Industry Association (EIA) Standard RS-485 and is 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 thermal-shutdown protection making it suitable for party-line applications in noisy environments. This device is designed using LinBiCMOS, facilitating ultra-low power consumption and inherent robustness.

The SN55LBC174 provides positive and negative-current limiting and thermal shutdown for protection from line fault conditions on the transmission bus line. This device offers optimum performance when used with the SN55LBC173 quadruple line receiver. The SN55LBC174 is available in the 16-pin CDIP package (J), the 16-pin CPAK (W), or the 20-pin LCCC package (FK).

The SN55LBC174 is characterized for operation over the military temperature range of 55°C to 125°C.
