The DS96F174 is a high speed quad differential line driver designed to meet EIA Standard RS-485. The DS96F174 offers improved performance due to the use of new, state-of-the-art L-FAST bipolar technology. The L-FAST technology allows for higher speeds and lower currents by utilizing extremely short gate delay times. Thus, the DS96F174 features lower power, extended temperature range, improved RS-485 specifications. The DS96F174 has wide positive and negative common mode range for multipoint applications in noisy environments. Positive and negative current-limiting is provided to protect the driver from line fault conditions over a + 12V to -7v common mode range. The DS96F174 features separate active high Enables for each driver pair.
