SN75118N datasheet by Texas Instruments

SN75118N Frequently Asked Questions (FAQs)

• What is the maximum data rate that the SN75118N can support?
  The SN75118N can support data rates up to 10 Mbps, making it suitable for high-speed applications such as industrial control systems and medical devices.
• How does the SN75118N handle common-mode noise and electromagnetic interference (EMI)?
  The SN75118N has a high common-mode rejection ratio (CMRR) of 80 dB, which helps to reject common-mode noise and EMI. Additionally, it has a built-in electromagnetic interference (EMI) filter to further reduce the effects of EMI.
• What is the maximum cable length that can be used with the SN75118N?
  The maximum cable length that can be used with the SN75118N depends on the data rate and the type of cable used. As a general rule, the maximum cable length is approximately 100 meters at 10 Mbps. However, this can be extended to several hundred meters at lower data rates.
• Can the SN75118N be used in half-duplex mode?
  Yes, the SN75118N can be used in half-duplex mode by connecting the transmitter output to the receiver input through a directional coupler or a switch. This allows the device to transmit and receive data on the same wire, but not simultaneously.
• What is the power consumption of the SN75118N?
  The power consumption of the SN75118N depends on the operating mode and the supply voltage. Typically, the device consumes around 20 mA of current from a 5V supply voltage. However, this can increase to around 30 mA at higher data rates or with heavier loads.
