ICL3241CV-T

Overview

The ICL3241CV-T is an RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for low-power serial communication applications. It integrates three drivers and five receivers within a single package, supporting full-duplex data transmission at rates up to 250 kb/s. The device operates on a supply voltage range of 3 V to 5.5 V, with a typical operating current of 1 mA. It features enhanced shutdown functionality to minimize standby power consumption. The component includes 15 kV ESD protection on all lines and utilizes small external capacitors due to efficient internal charge pumps. It is housed in an SSOP-28 surface-mount package and complies with RoHS standards.

Feature Summary

• Integrates three drivers and five receivers for comprehensive serial port implementation
• Features automatic and manual shutdown modes for ultra-low standby power consumption
• Provides 15 kV human-body model ESD protection on all RS-232 lines
• Supports operation with small-value external capacitors to reduce board space

Applications

• Portable computers and notebook systems requiring low power dissipation
• Personal digital assistants (PDAs) and handheld devices
• Industrial equipment with RS-232 connectivity needs
• Battery-powered systems utilizing 3V or 5V logic levels

Procurement Notes

Verify the specific suffix 'CV-T' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for SSOP-28 packages. Confirm moisture sensitivity level requirements for reflow soldering processes. Check for updated lead-free compliance status if required by local regulations. Validate that the 250 kbps data rate meets system timing constraints.

Selection Notes

Select this component when a combination of three transmit channels and five receive channels is required for RS-232 interfaces. It is suitable for designs prioritizing low quiescent current and effective ESD protection. Consider this part for mixed-voltage systems operating between 3.0 V and 5.5 V. Evaluate the SSOP-28 footprint availability against alternative packages like SOIC or QFN if space is constrained. Ensure the application does not require data rates exceeding 250 kbps.

Part Context

The ICL3241 series belongs to the ISL32xx family of RS-232 transceivers known for low power consumption. This family is widely used in portable electronics where battery life is critical. The ICL3241 variant specifically offers a 3-driver, 5-receiver configuration, distinguishing it from simpler 1-driver models. It maintains compatibility with earlier Intersil designs while offering improved ESD robustness and shutdown features.

Replacement Considerations

The ICL3243CV-T is a compatible alternative within the same family, offering identical pinout and electrical characteristics. Verify functional equivalence regarding driver/receiver counts and shutdown behavior before substitution.
