HIN211ECBZ

Overview

The HIN211ECBZ is a high-speed 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 supplies from the 5V input, eliminating the need for external dual-voltage sources. The device features four drivers and five receivers, supporting data rates up to 230 kb/s. It provides ±15kV ESD protection on transmitter outputs and receiver inputs, ensuring robust performance in harsh environments. The component operates within a temperature range of -40°C to +85°C and utilizes an SSOP-28 package.

Feature Summary

• Integrates onboard charge pump circuitry to generate internal voltage rails from a single 5V supply
• Provides ±15kV electrostatic discharge (ESD) protection on all RS-232 I/O pins
• Features low power shutdown mode for energy conservation in battery-powered applications
• Includes receiver hysteresis to significantly improve noise rejection capabilities

Applications

• High-speed RS-232 communications ports in portable and laptop computers
• Peripheral connections for printers and terminals
• Instrumentation systems and uninterruptible power supplies (UPS)
• ISDN terminal adaptors and high-speed modems

Procurement Notes

Verify the specific suffix 'CBZ' against official Renesas documentation to confirm exact packaging type, tape-and-reel specifications, and RoHS compliance status. Ensure the ordering part number matches the required pin configuration and moisture sensitivity level for your assembly process. Cross-reference with authorized distributors to validate current availability and lead times without relying on third-party stock claims.

Selection Notes

Select this component when designing systems requiring full-duplex RS-232 communication with four drivers and five receivers. It is suitable for applications where only a single 5V power rail is available, as it internally generates the required ±10V levels. Consider this part for designs needing high ESD immunity and low standby current through its shutdown feature. Verify that the 230 kb/s data rate meets the system's throughput requirements.

Part Context

The HIN211ECBZ belongs to the HIN211E family of RS-232 transmitters and receivers. This family is engineered to meet EIA high-speed RS-232E and V.28 specifications. Unlike older generations requiring ±12V supplies, this series operates exclusively on a single +5V source. The 'E' designation typically indicates enhanced features such as improved slew rates and higher ESD protection compared to standard variants.

Replacement Considerations

Direct replacements within the same family include HIN211EIAZ and HIN211EIBZ, which share similar functional characteristics but may differ in package style or temperature grade. Verify pin compatibility and electrical parameters before substitution. Other members of the HINxxxE series, such as HIN206E or HIN213E, offer different driver/receiver counts and should be evaluated based on specific interface needs.
