ISL32277EFRZ-T - Renesas Electronics

Description: These Renesas devices are ±16. 5kV IEC61000-4-2 ESD protected, 3. 0V to 5. 5V powered, quad receivers for balanced communication using the RS-485 and RS-422 standards. Each receiver has low input currents (±200μA), so it presents a 1/4 unit load to the RS-485 bus and allows up to 128 receivers on the bus. The ISL32173E and ISL32177E are high data rate receivers that operate at data rates up to 80Mbps. Their 8ns maximum propagation delay skew (tolerance) ensures excellent part-to-part matching. The ISL32273E

ISL32277EFRZ-T Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in the application note AN1995, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The ISL32277EFRZ-T has a thermal pad that must be connected to a thermal plane on the PCB to dissipate heat. A thermal via array or a copper pour on the PCB can be used to dissipate heat. Additionally, the device has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C.
  • The recommended input capacitor value is 1uF to 10uF, and the type should be a low-ESR ceramic capacitor, such as X5R or X7R, to minimize input ripple and ensure stable operation.
  • The output voltage of the ISL32277EFRZ-T can be adjusted by connecting a resistor divider network between the output and the FB pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
  • The absolute maximum input voltage rating for the ISL32277EFRZ-T is 18V, but the recommended maximum input voltage is 15V to ensure reliable operation and minimize stress on the device.
