Description:The ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, and ICL3243E are 3. 0V to 5. 5V powered RS-232 transmitters/receivers that 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 notebook and laptop computers in which the low operational power consumption and even lower standby power consumption is critical. Effici
Renesas recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signal traces separate. Additionally, use a ferrite bead or a 10-ohm resistor in series with the VCC pin to reduce high-frequency noise.
Make sure to provide adequate heat sinking, especially in high-power applications. Use a thermal pad or a heat sink with a thermal conductivity of at least 1 W/m-K. Also, ensure good airflow around the device and avoid blocking the airflow with nearby components.
The maximum cable length for the ICL3243ECBZ's RS-232 transceiver is approximately 50 feet (15.24 meters) at a data rate of 115.2 kbps. However, this can vary depending on the cable quality, noise environment, and data rate.
Yes, the ICL3243ECBZ can operate from a single 3.3V supply. However, the device's output voltage swing will be reduced, and the maximum data rate may be limited to 9600 bps. Consult the datasheet for specific details on 3.3V operation.
To enter shutdown mode, drive the SHDN pin low. In shutdown mode, the device's power consumption is reduced to less than 1 μA. When exiting shutdown mode, ensure the SHDN pin is driven high for at least 100 ns before transmitting data.
