ISL4245EIRZ - Renesas Electronics

Description: The Intersil ISL4238E, ISL4244E and ISL4245E devices are 2. 7V to 5. 5V powered RS-232 transmitters/receivers which meet ElA/TIA-232 and V. 28/V. 24 specifications, even at VCC = 3. 0V. Additionally, they provide ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are PDAs, Palmtops, and notebook and laptop computers where the low operational, and even lower standby power consumption is critical. Efficient on-chip c

ISL4245EIRZ Frequently Asked Questions (FAQs)

  • A good PCB layout for the ISL4245EIRZ involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. A 4-layer PCB with a dedicated ground plane is recommended.
  • To ensure proper power-up and power-down of the ISL4245EIRZ, make sure to follow the recommended power-up sequence, which is VCC first, then VDD, and finally VLOGIC. During power-down, reverse this sequence. Also, ensure that the input voltage ramps up and down slowly to prevent latch-up.
  • The ISL4245EIRZ has a maximum junction temperature of 150°C. To ensure reliable operation, keep the device's operating temperature below 125°C. Use thermal vias and a heat sink if necessary, and ensure good airflow around the device.
  • The ISL4245EIRZ has built-in ESD protection, but it's still important to follow proper ESD handling procedures during assembly and testing. Use an ESD wrist strap or mat, and ensure that all equipment is properly grounded.
  • The ISL4245EIRZ requires high-quality, low-ESR capacitors with a minimum capacitance of 10uF. X5R or X7R ceramic capacitors are recommended, and they should be placed as close to the device as possible.
