ICL3244ECAZ-TS2705

Overview

The ICL3244ECAZ-TS2705 is a triple line transceiver manufactured by Renesas Electronics, designed for RS-232 communication applications. It integrates three drivers and five receivers within a single package, supporting data rates up to 1Mbps. The device operates on a single 3.3V or 5V power supply and features Schmitt trigger inputs for noise immunity. It is housed in a 28-pin SSOP surface-mount package with dimensions of 10.5mm x 5.6mm x 1.85mm. The component functions reliably across an operating temperature range from 0°C to +70°C, complying with EIA-232, TIA-232, V.24, and V.28 interface standards.

Feature Summary

• Integrates three independent drivers and five independent receivers for comprehensive serial communication
• Features Schmitt trigger inputs on all receivers to enhance noise rejection capabilities
• Supports operation from a single 3.3V or 5V power supply without requiring external negative voltages
• Complies with major RS-232 interface standards including EIA-232 and TIA-232

Applications

• Industrial control systems requiring reliable serial data transmission
• Point-of-sale (POS) terminals and barcode scanners
• Medical equipment with serial communication interfaces
• Computer peripheral connections and modem interfaces

Procurement Notes

Verify the authenticity of the TS2705 suffix, as standard datasheets typically list ICL3244ECAZ. Confirm that the suffix denotes a specific tape-and-reel packaging variant or manufacturing batch code rather than a functional change. Ensure the supplier provides traceability documentation matching the Renesas part number to avoid counterfeit components.

Selection Notes

Select this component when a triple driver and five receiver configuration is required for RS-232 links. It is suitable for designs needing low-power operation from a single voltage rail. Compare pin compatibility with legacy Intersil versions if replacing existing circuits. Verify that the SSOP package footprint matches the target PCB layout constraints.

Part Context

This part belongs to the ICL324x family of RS-232 transceivers, which are widely used in embedded systems. The ICL3244 specifically offers an asymmetric driver/receiver count compared to symmetric variants like the ICL3243. It represents a continuation of the industry-standard MAX3243 architecture under the Renesas brand following the Intersil acquisition.

Replacement Considerations

Direct pin-compatible substitutes include the MAX3243EIA+ from Maxim Integrated and the SP3243EEI from MaxLinear. These alternatives offer similar electrical characteristics and functionality. Verify that any replacement supports the same 3.3V/5V supply requirements and SSOP package dimensions.
