SN75C189AD datasheet by Texas Instruments

SN75C189AD Frequently Asked Questions (FAQs)

• What is the maximum data rate that the SN75C189AD can support?
  The SN75C189AD can support data rates up to 100 Mbps, making it suitable for high-speed applications such as video transmission and high-speed data acquisition.
• How does the SN75C189AD handle common-mode noise and electromagnetic interference (EMI)?
  The SN75C189AD has a high common-mode rejection ratio (CMRR) of 80 dB, which helps to reject common-mode noise and EMI. Additionally, the device has a shielded pinout that helps to reduce radiated emissions and improve immunity to external noise.
• What is the power consumption of the SN75C189AD, and how does it affect the overall system power budget?
  The SN75C189AD has a low quiescent current of 10 mA, which makes it suitable for power-sensitive applications. The device also has a shutdown mode that reduces the power consumption to less than 1 μA, allowing for further power savings.
• How does the SN75C189AD handle signal skew and jitter, and what are the implications for system design?
  The SN75C189AD has a skew of less than 1 ns, which helps to minimize signal distortion and ensure reliable data transmission. The device also has a jitter tolerance of up to 1 ns, making it suitable for applications that require low jitter and high signal integrity.
• What are the thermal considerations for the SN75C189AD, and how does it affect the overall system design?
  The SN75C189AD has a junction-to-ambient thermal resistance of 30°C/W, which means that it can operate reliably in high-temperature environments. However, it's still important to ensure proper thermal design and heat sinking to prevent overheating and ensure reliable operation.
