ICL3241ECV-T

Overview

The ICL3241ECV-T is a low-power RS-232 transceiver manufactured by Intersil, designed for operation with a single +3V to +5.5V power supply. It integrates three drivers and five receivers, supporting full-duplex communication at data rates up to 250 kb/s. The device features a shutdown mode that reduces supply current to approximately 1 µA. It includes enhanced automatic powerdown circuitry to minimize power consumption during idle periods. The component provides 15 kV electrostatic discharge (ESD) protection on all RS-232 lines and operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates three independent drivers and five independent receivers for comprehensive RS-232 connectivity.
• Features enhanced automatic powerdown circuitry that places the device in low-power shutdown when no valid signal is present.
• Provides robust 15 kV ESD protection on all RS-232 input and output lines.

Applications

• Portable computers and notebook systems requiring low-power serial communication.
• Battery-powered industrial equipment utilizing RS-232 interfaces.
• Modems and handheld devices with strict power consumption constraints.

Procurement Notes

Verify the specific suffix 'ECV' against official Renesas/Intersil documentation to confirm package type and tape-and-reel configuration. Ensure the operating voltage range matches the system design requirements. Confirm moisture sensitivity level handling procedures are followed during assembly. Cross-reference the manufacturer part number with current datasheets to validate active status and availability.

Selection Notes

Select this component when three drivers and five receivers are required in a single package. It is suitable for applications needing low standby current due to its shutdown capability. Consider the SSOP or similar compact package if space is limited. Verify compatibility with 3V and 5V logic levels. Ensure the 250 kb/s speed meets the application's baud rate requirements.

Part Context

This part belongs to the ICL3241 series of RS-232 transceivers from Intersil, now part of Renesas Electronics. The series is known for low-power operation and high ESD protection. The ICL3241 variant specifically offers a higher receiver count compared to simpler dual-driver versions, making it versatile for complex serial interfaces.

Replacement Considerations

Check for direct pin-compatible substitutes such as the MAX3241 or SP3241 series. Verify that alternative components support the same 3V to 5.5V supply range and 250 kb/s data rate. Ensure equivalent ESD protection levels and shutdown functionality are present in any replacement part.
