ICL3241ECAZ-T

Overview

The ICL3241ECAZ-T is a single-supply RS-232 transceiver manufactured by Renesas Electronics. It operates within a voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device integrates three drivers and five receivers in a full-duplex configuration, housed in an SSOP-28 package. It features a shutdown mode with a typical operating supply current of 1 mA. The component provides 15 kV ESD protection on RS-232 lines and functions across a temperature range of 0°C to +70°C.

Feature Summary

• Integrates three independent drivers and five independent receivers for comprehensive serial communication interfaces.
• Includes manual shutdown functionality to minimize power consumption during idle periods.
• Provides robust electrostatic discharge protection rated at 15 kV on all RS-232 signal lines.

Applications

• Portable computing devices such as PDAs and laptops requiring low-power serial connectivity.
• Industrial control systems utilizing mixed 3.3V and 5.0V logic levels.
• Embedded systems needing reliable RS-232 communication with enhanced ESD resilience.

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure handling procedures account for moisture sensitivity classification to prevent damage during assembly processes.

Selection Notes

Select this component when designing circuits requiring multiple transmit and receive channels within a single IC. It is suitable for applications demanding low standby current and high ESD immunity. Verify that the required data rate does not exceed 250 kb/s and that the system voltage aligns with the 3 V to 5.5 V operational range.

Part Context

This part belongs to the ICL324x family of RS-232 transceivers designed for portable electronics. It shares architectural similarities with other members like the ICL3243 but offers a distinct driver-to-receiver ratio. The family targets battery-operated devices where power efficiency and board space conservation are critical design constraints.

Replacement Considerations

The ICL3243CAZ-T serves as a functional substitute within the same series, offering identical electrical characteristics and pinout compatibility. Both parts share the same package type and operational specifications, allowing for direct interchangeability in existing designs without circuit modification.
