What is SN65C1168EPWG4 used for?
SN65C1168EPWG4 is used in industrial automation networks, CNC machine tool controllers, and process control systems where RS-422 balanced differential signaling is required to transmit serial data over cable lengths up to 1200 meters with high noise immunity. It suits point-to-point and multi-drop communication links in factory equipment, PLC I/O modules, and building automation backbones. The dual-channel configuration allows simultaneous full-duplex transmit and receive operations on a single IC in half-duplex or full-duplex RS-422 topologies.

Frequently Asked Questions
What communication standard does SN65C1168EPWG4 implement, and at what data rate?
SN65C1168EPWG4 implements the EIA-422-B and TIA-422-B (also known as V.11) differential serial communication standard, supporting data rates up to 10 Mbps at short cable lengths and lower rates over cable runs extending to 1200 meters. The differential balanced line signaling provides robust noise rejection in electrically noisy industrial environments.
How does the differential Schmitt-trigger receiver input of SN65C1168EPWG4 improve signal integrity?
The differential Schmitt-trigger inputs in SN65C1168EPWG4 add hysteresis to the receiver threshold, typically around 50 mV to 200 mV, preventing false triggering from noise or slow signal edges on long cable runs. This is critical in factory automation and building control wiring where electromagnetic interference from motors, VFDs, and relay coils can corrupt single-ended serial links.
For a PLC or CNC serial network, how many channels does SN65C1168EPWG4 provide per package?
SN65C1168EPWG4 integrates 2 differential drivers and 2 differential receivers in a single 16-pin TSSOP package, enabling full-duplex RS-422 communication for one channel or half-duplex operation for 2 independent channels. This dual configuration reduces IC count and PCB area compared to using 2 separate single-channel transceivers in designs like servo drive interfaces or CNC axis controllers.
Over what cable distance can SN65C1168EPWG4 reliably transmit RS-422 signals?
Under EIA-422-B guidelines, SN65C1168EPWG4 can drive balanced differential signals over twisted-pair cable up to approximately 1200 meters at low data rates (below 100 kbps), or up to several tens of meters at the maximum 10 Mbps data rate. The actual distance-rate trade-off depends on cable capacitance, termination resistance, and noise environment in the specific installation.
