Overview
The Intersil ICL3238ECV is a low-power RS-232 transceiver designed for operation with supply voltages ranging from +3.0 V to +5.5 V. It integrates five drivers and three receivers, supporting full-duplex communication at data rates up to 250 kbps. The device features an automatic powerdown function that reduces standby current to approximately 1 µA when no valid signal is detected on the receiver inputs. It provides ±15 kV electrostatic discharge (ESD) protection on both RS-232 I/O pins and logic pins, ensuring robustness in harsh environments. The component operates within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Integrates five drivers and three receivers for comprehensive serial communication interfaces.
- Features automatic powerdown circuitry to minimize standby power consumption.
- Provides ±15 kV ESD protection on RS-232 I/O and logic pins.
Applications
- ISDN Terminal Adaptors
- Personal Digital Assistants (PDAs)
- Notebook and laptop computers
Procurement Notes
Verify the specific suffix 'ECV' against official Intersil or Renesas documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding capacitor values and pin configurations before procurement.
Selection Notes
Select this component for applications requiring low power consumption in portable devices. Verify that the required number of drivers and receivers matches the system design. Confirm that the operating voltage range aligns with the system's power supply rails.
Part Context
The ICL3238E belongs to the Intersil ICL32XXE family of low-power RS-232 transceivers. This series is engineered for battery-powered systems where power efficiency is critical. The device meets EIA/TIA-232 and V.28/V.24 specifications even at lower supply voltages.
Replacement Considerations
The MAX3238ECAI+T from Analog Devices/Maxim Integrated is a functional equivalent with similar electrical characteristics. Verify pinout compatibility and capacitor requirements before substitution.
