ICL3207ECBZ-T

Overview

The ICL3207ECBZ-T is an RS-232 transceiver manufactured by Renesas Electronics, belonging to the ICL3207E series. It integrates five drivers and three receivers within a single package. The device operates on a supply voltage ranging from 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. It achieves data rates up to 500 kb/s while maintaining low power consumption with a typical operating current of 1 mA. The component features integrated charge pumps for generating required RS-232 voltages without external inductors. It includes ESD protection on all RS-232 pins rated at ±15 kV (Human Body Model). The unit is housed in a 24-pin SSOP package suitable for surface mount applications.

Feature Summary

• Integrates five drivers and three receivers for multi-port serial communication
• Provides ±15 kV ESD protection on RS-232 I/O pins
• Operates efficiently across 3 V to 5.5 V supply ranges
• Features automatic powerdown functionality to minimize standby current

Applications

• ISDN Terminal Adaptors
• Portable computing devices such as PDAs and Palmtops
• Notebook and laptop computer peripheral interfaces

Procurement Notes

Verify the specific suffix 'ECBZ' against official Renesas documentation to confirm lead-free status and temperature grade. Confirm availability as the base ICL3207 family may have discontinued variants. Ensure the tape and reel quantity matches project requirements. Validate RoHS compliance through the manufacturer's current ordering information.

Selection Notes

Select this component when designing systems requiring multiple RS-232 channels with strict power constraints. It serves as a low-power replacement for older 5 V-only transceivers. Consider the 24-pin SSOP footprint for board space limitations. Verify that the 500 kb/s speed meets the application's baud rate needs.

Part Context

This part belongs to the ICL32X7E family of low-power RS-232 transmitters and receivers. The family is designed to meet EIA/TIA-232 and V.28/V.24 specifications even at 3.0 V. The 'E' suffix typically denotes an extended industrial temperature range compared to commercial variants.
