SN75121N Frequently Asked Questions (FAQs)

  • The SN75121N can support data rates up to 10 Mbps, making it suitable for high-speed applications such as industrial control systems and medical devices.
  • The SN75121N 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.
  • The maximum cable length that can be used with the SN75121N 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, but this can be extended to several hundred meters at lower data rates.
  • Yes, the SN75121N 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.
  • The power consumption of the SN75121N depends on the operating mode and the supply voltage. Typically, the device consumes around 20-30 mA of current from a 5V supply voltage, making it suitable for battery-powered devices.
