HIN207EIAZ

Overview

The HIN207EIAZ is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for single +5V power supply operation. It integrates onboard charge pump voltage converters to generate the necessary positive and negative voltages from the 5V input, eliminating the need for external ±12V supplies. The device features three drivers and two receivers, supporting data rates up to 230 kbps. It provides high ESD protection of ±15kV on RS-232 I/O pins and includes a low-power shutdown mode with typical current consumption of 1µA. The component meets EIA RS-232E and V.28 specifications.

Feature Summary

• Single +5V power supply operation with integrated onboard charge pump voltage converters generating ±10V supplies
• High electrostatic discharge (ESD) protection rated at ±15kV on RS-232 input and output pins
• Low-power shutdown mode functionality to conserve energy in battery-powered applications
• TTL/CMOS compatible inputs and outputs with slew rate-limited drivers for noise reduction

Applications

• ISDN terminal adapters and high-speed modem interfaces
• Battery-powered portable equipment requiring low standby current
• Industrial control systems needing robust ESD protection on serial ports
• Embedded systems utilizing standard RS-232 communication protocols

Procurement Notes

Verify the specific suffix 'IAZ' corresponds to the SSOP-24 package and lead-free RoHS compliance status as documented in the official datasheet. Confirm that the ordering information matches the exact pinout and electrical characteristics required for the target design, as variations may exist across different manufacturing revisions or regional certifications.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are not. The HIN207EIAZ is appropriate for designs requiring three transmit channels and two receive channels. Consider the low-power shutdown feature if battery life is critical. Ensure the PCB layout accommodates the required 0.1µF or greater external capacitors for the charge pump circuitry to maintain signal integrity at speeds up to 230 kbps.

Part Context

The HIN207EIAZ belongs to the HIN20xE family of RS-232 transceivers, which also includes models like the HIN202E, HIN206E, and HIN213E. This family shares common architectural features such as onboard charge pumps and high ESD protection. The HIN207E specifically distinguishes itself within the series by offering three drivers and two receivers, providing more transmission channels than the dual-driver variants while maintaining compatibility with standard RS-232 signaling levels.

Replacement Considerations

Direct functional substitutes within the same family include the HIN207EIBZ (PDIP-24 package). Cross-manufacturer equivalents should be verified for pin compatibility and electrical parameters, particularly the charge pump capacitor requirements and ESD protection ratings.
