Frequently Asked Questions - SN75C1168NSR TEXAS INSTRUMENTS
What is the SN75C1168NSR used for?
The SN75C1168NSR is a dual differential line driver and receiver used for RS-422 and RS-485 communication networks. It enables reliable data transmission over long distances in industrial automation, building control, and data acquisition systems.
What is the maximum data rate supported?
The SN75C1168NSR supports data rates up to 10 Mbps, making it suitable for high-speed serial communication in industrial applications.
What is the supply voltage range?
The device operates with a supply voltage ranging from 4.5V to 5.5V, with a typical supply of 5V. This is compatible with standard TTL and CMOS power rails.
How many drivers and receivers does it contain?
The SN75C1168NSR integrates two drivers and two receivers in a single package, providing a complete interface solution for full-duplex communication.
What is the difference between RS-422 and RS-485?
Both standards use differential signaling, but RS-422 supports one driver and up to 10 receivers, while RS-485 allows up to 32 drivers and 32 receivers on the same bus, enabling multi-point networks.
Can the SN75C1168NSR be used with 3.3V logic?
The device is designed for 5V operation. However, its input thresholds are TTL-compatible, and it can interface with 3.3V logic when appropriate level shifting is used.
What is the package type of this component?
The SN75C1168NSR comes in an SOP-16 package (Small Outline Package), which is a surface-mount package suitable for automated assembly and compact PCB designs.
How do I connect the SN75C1168NSR in a typical RS-485 network?
Connect the driver outputs (A and B) to the differential bus lines, the receiver inputs (Y and Z) also to the bus via a termination resistor if needed. Use the enable pins to control driver/receiver activity. Proper bus termination with 120Ω resistors helps minimize reflections.
What are the operating temperature limits?
The device operates over an industrial temperature range from -40°C to +85°C, making it suitable for harsh environments.
Is the component RoHS compliant?
Yes, the SN75C1168NSR is RoHS compliant and lead-free, meeting current environmental standards for electronic components.
