ICL3241CVZ-T

Overview

The ICL3241CVZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, operating within a supply voltage range of 3.0V to 5.5V. It integrates three drivers and five receivers, supporting data rates up to 250Kbps while complying with EIA/TIA-232 and V.28/V.24 standards. The device features ±15kV electrostatic discharge (ESD) protection on both transmitter outputs and receiver inputs. It includes an efficient on-chip charge pump and offers manual and automatic shutdown modes to minimize standby power consumption. The component is housed in a TSSOP-28 surface-mount package and operates reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates three drivers and five receivers for comprehensive serial port connectivity
• Provides ±15kV ESD protection on RS-232 pins per IEC61000-4-2 standards
• Features automatic shutdown functionality to reduce system power consumption when peripherals are disconnected

Applications

• Personal Digital Assistants (PDAs)
• Laptop computers
• Portable computing devices

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.

Selection Notes

Select this component when designing systems requiring multiple transmit and receive lines within a single interface channel. It is suitable for applications needing robust ESD protection and low standby current in portable electronics. Verify that the TSSOP-28 package dimensions fit the available PCB real estate constraints.

Part Context

This device belongs to the Intersil ICL32xE series of RS-232 transceivers designed for 3.0V to 5.5V operation. The series targets portable applications where power efficiency and space savings are critical. The ICL3241 variant specifically provides the driver and receiver counts necessary for full serial port implementations in compact form factors.
