ICL3232IBNZ-T7A

Overview

The ICL3232IBNZ-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 on a single power supply ranging from 3 V to 5.5 V. It utilizes a 16-pin Narrow SOIC (SOIC-N) surface-mount package. The component is rated for an operating temperature range of -40°C to +85°C. Key electrical specifications include a receiver hysteresis of 300 mV and ±15 kV ESD protection on all pins.

Feature Summary

• Integrated dual driver and dual receiver architecture for full-duplex communication
• Robust electrostatic discharge protection rated at ±15 kV across all interfaces
• Single-supply operation capability spanning 3 V to 5.5 V ranges
• Receiver input hysteresis designed to filter noise and ensure signal integrity

Applications

• Industrial control systems requiring reliable serial communication
• Point-of-sale terminals and barcode scanners
• Medical equipment with serial interface requirements
• Embedded systems utilizing RS-232 protocols

Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging configuration. Ensure the part number matches the exact manufacturer designation to avoid confusion with similar variants in the ICL3232 family. Cross-reference the RoHS status and moisture sensitivity level during procurement planning.

Selection Notes

Select this component when a compact surface-mount solution is required for dual-channel RS-232 applications. The narrow SOIC package suits space-constrained designs. Confirm that the 250 kbps data rate meets system requirements. Verify compatibility with the target voltage domain between 3 V and 5.5 V before integration into the circuit design.

Part Context

This part belongs to the ICL3232 series of RS-232 transceivers produced by Renesas Electronics. The series is known for low power consumption and high reliability in industrial environments. The ICL3232IBNZ variant typically denotes the industry temperature grade and standard tube packaging, while the T7A suffix indicates a specific reel-based packaging option for automated assembly.

Replacement Considerations

Direct substitutes include ICL3232IBNZ and ICL3232IVZ. Verify pinout compatibility and package dimensions before substitution. Check if alternative versions meet the same -40°C to +85°C operating temperature range and 250 kbps speed specification.
