ISL4223EIRZ-T7A - Renesas Electronics

Description: The ISL3232E, ISL4221E, and ISL4223E devices are 2. 7V to 5. 5V powered RS-232 transmitters/receivers that meet ElA/TIA-232 and V. 28/V. 24 specifications, even at VCC = 3. 0V. 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 hand-held products where the low operational power consumption and even lower standby power consumption are critical. Efficient on-chip charge pumps, cou

ISL4223EIRZ-T7A Frequently Asked Questions (FAQs)

  • A good PCB layout for the ISL4223EIRZ-T7A 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 and decoupling, use a high-quality, low-ESR capacitor (e.g., 10uF ceramic) between VCC and GND, and a 100nF capacitor between VCC and AVCC. Place these capacitors as close to the device as possible.
  • The ISL4223EIRZ-T7A can achieve data rates up to 100Mbps, but the actual data rate may vary depending on the specific application, cable length, and noise environment.
  • To protect the ISL4223EIRZ-T7A from ESD, use a TVS (Transient Voltage Suppressor) diode or a dedicated ESD protection device, such as the Renesas ESD protection IC, in conjunction with a 1kΩ resistor in series with the data lines.
  • The recommended termination scheme for the ISL4223EIRZ-T7A is a 100Ω differential termination resistor at the receiver end, and a 50Ω to 100Ω series termination resistor at the transmitter end.
