Frequently Asked Questions
How many differential output channels does the SN75ALS192DG4 provide, and what RS-422 standard does it meet?
The SN75ALS192DG4 integrates 4 differential line driver channels, all compliant with EIA-422-B and TIA-422-B interface standards. Each channel produces a balanced differential output signal that can drive cable runs over long distances, with common-mode noise rejection making it suitable for industrial environments with significant electromagnetic interference.
What cable length can an RS-422 system using the SN75ALS192DG4 reliably drive?
RS-422 systems using the SN75ALS192DG4 can reliably transmit data over cable runs up to 1200 meters at lower data rates. At higher data rates approaching 10 Mbps, the maximum cable length decreases due to signal degradation, but the differential balanced output of each of the 4 driver channels maintains solid noise margin even over industrial-grade twisted pair cables in the 100-meter to 300-meter range.
Can the SN75ALS192DG4 be used to drive multiple serial lines from a single microcontroller UART?
With 4 independent driver channels in one 16-pin SOIC package, the SN75ALS192DG4 allows a designer to multiplex or independently drive up to 4 RS-422 lines from a microcontroller with multiple UART peripherals. This reduces component count versus using 4 single-channel line drivers, and the maximum input current of 20 µA per input makes it easy to drive from 3.3V or 5V logic GPIO pins.
