ISL32179EFRZ - Renesas Electronics

Description: The ISL32172E, ISL32272E, ISL32174E, and ISL32179E are ±16. 5kV IEC61000-4-2 ESD protected, 3. 0V to 5. 5V powered, QUAD transmitters for balanced communication using the RS-422 standard. These drivers have very low output leakage currents (±10µA), so they present a low load to the RS-422 bus. The driver (Tx) outputs are tri-statable and incorporate a hot plug feature to keep them disabled during power-up and power-down. The ISL32172E and ISL32272E have a common EN/EN, the ISL32174E has a two channel EN12/E

ISL32179EFRZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog and digital power plane is recommended. Keep the analog and digital signals separate and avoid crossing them over each other.
  • Ensure good thermal conductivity by using a heat sink or a thermal pad, and avoid blocking airflow around the device. Also, follow the recommended PCB layout and thermal design guidelines.
  • A 10uF to 22uF ceramic capacitor is recommended for the input pin to ensure stable operation and reduce noise.
  • Use ESD protection devices such as TVS diodes or ESD arrays on the input and output lines to protect the device from electrostatic discharge.
  • Power up the device in the following sequence: VCC, then VIN, and finally the input signal. This ensures proper device operation and prevents latch-up.
