ICL3241EIAZ-T

Overview

The ICL3241EIAZ-T is an RS-232 transceiver from the ICL32xxE series manufactured by Renesas Electronics. It features one driver and five receivers, supporting data rates up to 500 kb/s. The device operates on a single power supply ranging from 3 V to 5.5 V, with typical operation at 3.3 V or 5 V. It includes an efficient on-chip charge pump and offers ±15 kV ESD protection on RS-232 pins per IEC61000-4-2 standards. The part is housed in a 28-pin SSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides full RS-232 functionality with one driver and five receivers for complete serial port implementation.
• Integrates ±15 kV electrostatic discharge protection on transmitter outputs and receiver inputs.
• Features manual shutdown mode that reduces supply current to microampere levels.

Applications

• Personal digital assistants (PDAs) and handheld computers
• Laptops and portable computing devices
• Systems requiring low standby power consumption

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'E' designation aligns with industrial temperature specifications (-40°C to +85°C). Ensure compatibility with 3.3 V and 5 V logic systems. Check RoHS compliance status as required by project regulations. Validate pinout alignment with SSOP-28 footprint designs.

Selection Notes

Select this component for applications requiring multiple receive lines alongside a single transmit line. It suits designs needing robust ESD protection without external components. Consider the 500 kb/s speed limit for high-speed serial links. Evaluate the SSOP-28 package size against available board space. Verify power supply constraints match the 3 V to 5.5 V operating range.

Part Context

This part belongs to the ICL32xxE family of CMOS RS-232 transceivers. It shares architectural similarities with the ICL3243E and ICL3244E but differs in driver and receiver counts. The ICL3241 specifically provides one driver and five receivers, distinguishing it from dual-driver variants. It utilizes the same charge pump technology and shutdown features found across the E-series lineup.

Replacement Considerations

The ICL3241EIVZ serves as a functional equivalent in TSSOP-28 packaging. The ICL3244EIAZ offers identical electrical performance in SSOP-28 format. Verify pin-to-pin compatibility before substitution. Confirm package dimensions differ if switching between SSOP and TSSOP variants.
