ICL3244ECAZ-T

Overview

The ICL3244ECAZ-T is a single-supply RS-232 transceiver manufactured by Renesas Electronics. It operates from a +3V to +5.5V power supply and supports data rates up to 250 kb/s. The device integrates three drivers and five receivers in a full-duplex configuration. It features enhanced automatic power-down functionality, reducing standby current to 1 mA. ESD protection is rated at 15 kV. The component is housed in a 28-pin SSOP package and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated three drivers and five receivers for comprehensive serial communication
• Enhanced automatic power-down function reduces standby power consumption
• High electrostatic discharge protection rating of 15 kV
• Compatible with single +3V to +5.5V power supplies

Applications

• Industrial control systems requiring robust RS-232 connectivity
• Portable equipment utilizing low-power serial interfaces
• Communication modules needing high ESD tolerance

Procurement Notes

Verify the exact part number suffix against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements before procurement. Check for moisture sensitivity levels and storage conditions as indicated in the datasheet. Confirm that the reel packaging matches production line specifications.

Selection Notes

Select this component when three transmit and five receive channels are required in a compact surface-mount package. The industrial temperature range makes it suitable for harsh environments. Consider the 250 kb/s data rate limit and ensure it meets application timing requirements. Verify that the automatic power-down feature aligns with system sleep modes.

Part Context

This part belongs to the ICL324x family of RS-232 transceivers designed for low-power applications. It shares architectural similarities with other members like the ICL3243 but offers specific driver and receiver counts. The 'T' suffix indicates tape and reel packaging, distinguishing it from tube-packaged variants.

Replacement Considerations

Direct substitutes include the ICL3243ECAZ if fewer receivers are acceptable. Verify pinout compatibility and electrical parameters before substitution. Alternative packages may require schematic adjustments.
