ICL3232ECAZ-T7A

Overview

The ICL3232ECAZ-T7A is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates two drivers and two receivers within a single package, supporting data rates up to 250 kbps. The device operates from a single power supply ranging from 3 V to 5.5 V. It utilizes external capacitors for charge pump functionality to generate the required positive and negative voltages for RS-232 signaling. The component is designed for surface mount installation in a 16-TSSOP package with a width of 4.40 mm. It functions reliably across an extended industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual drivers and dual receivers for complete full-duplex communication capability
• Operates on a single low-voltage power supply without requiring external negative voltage generation circuits
• Includes internal circuitry to generate required RS-232 voltage levels using only small external capacitors
• Provides high noise immunity through receiver hysteresis to prevent false triggering

Applications

• Battery-powered portable equipment and handheld devices
• Industrial control systems requiring RS-232 connectivity
• Modems and peripheral interface connections
• Embedded systems utilizing serial communication protocols

Procurement Notes

Verify the specific suffix 'ECAZ' against official Renesas documentation to confirm exact temperature grade and packaging specifications. Ensure compatibility with RoHS3 standards if environmental compliance is required. Confirm moisture sensitivity level handling procedures during assembly to prevent damage. Cross-reference the manufacturer part number with authorized distributor databases to validate authenticity and current production status.

Selection Notes

Select this component when a full-duplex RS-232 interface is needed with low power consumption constraints. It is suitable for designs operating between 3 V and 5.5 V where space is limited due to the TSSOP footprint. Consider the 250 kbps data rate limit for application speed requirements. Verify that the external capacitor selection meets the stability requirements for the charge pump circuit under varying load conditions.

Part Context

This part belongs to the ICL3232 family of line transceivers produced by Renesas Electronics. The family typically includes variants with different suffixes indicating package type or temperature range. The base model supports standard RS-232 communication standards including EIA/TIA-232. The T7A suffix generally indicates tape and reel packaging for automated assembly processes.

Replacement Considerations

Direct substitutes include other 2/2 driver/receiver RS-232 transceivers in 16-TSSOP packages such as the MAX3232 series. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Alternative parts must support the same 3 V to 5.5 V supply range and meet the 250 kbps data rate specification.
