HIN213EIBZ

Overview

The HIN213EIBZ is a full-duplex RS-232 transceiver manufactured by Renesas Electronics. It operates from a single +5V supply and includes onboard charge pumps to generate the required ±10V levels, eliminating the need for external dual supplies. The device features five receivers and two drivers, supporting data rates up to 230 kbps. It provides ±15kV ESD protection on I/O pins per IEC61000 standards. Key electrical parameters include a minimum supply voltage of 4.5V, maximum of 5.5V, and an operating temperature range of -40°C to +85°C. The package is SSOP with 28 leads.

Feature Summary

• Integrated onboard voltage doubler and inverter generates ±10V supplies from a single +5V source using only 0.1µF external capacitors.
• Low power shutdown mode reduces current consumption to typical 1µA while maintaining two active receivers for system wakeup capability.
• High ESD protection rated at ±15kV on RS-232 I/O pins ensures robustness against electrostatic discharge events.
• TTL/CMOS compatible inputs and outputs with hysteresis improve noise rejection and signal integrity.

Applications

• ISDN terminal adapters and high-speed modem interfaces
• Battery-powered equipment requiring low standby current
• Industrial control systems needing reliable serial communication

Procurement Notes

Verify the specific suffix 'IBZ' against official Renesas documentation to confirm pinout and package dimensions match the SSOP-28 form factor. Ensure compliance with RoHS directives if lead-free status is required for the assembly process. Cross-reference the manufacturer date code with current production status to avoid obsolete stock issues during long-term manufacturing runs.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 voltage levels are needed. The inclusion of five receivers makes it suitable for multi-drop bus configurations or systems requiring multiple input lines. The shutdown feature is critical for portable devices where power conservation is a priority compared to always-on alternatives.

Part Context

The HIN213EIBZ belongs to the HINE family of RS-232 transceivers, which also includes models like HIN202E, HIN206E, and HIN232E. This family shares common architecture features such as onboard charge pumps and ESD protection. The HIN213E variant specifically distinguishes itself by offering a higher receiver count and dedicated wakeup functionality in shutdown mode.

Replacement Considerations

Direct functional substitutes within the same family include HIN213EIAZ. Verify that alternative packages such as SOIC or PDIP meet the physical space constraints of the design. Ensure that any replacement maintains the same 230 kbps data rate and ±15kV ESD protection ratings.
