HIN211EIAZ-T

Overview

The HIN211EIAZ-T is a quad driver, five receiver RS-232 transceiver manufactured by Renesas Electronics. It operates on a single +5V supply with onboard charge pumps generating ±10V. The device supports data rates up to 230 kb/s and meets EIA high-speed RS-232E and V.28 specifications. It features ±15kV ESD protection on I/O pins, low power shutdown mode consuming typically 1µA, and TTL/CMOS compatible inputs. The package is SSOP-28 with an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump voltage converters generate required positive and negative supplies from a single 5V source.
• High electrostatic discharge protection rated at ±15kV on transmitter outputs and receiver inputs.
• Low power shutdown function significantly reduces current consumption for battery-powered applications.
• Receiver inputs include hysteresis to enhance noise rejection capabilities.

Applications

• Portable computers and laptop systems requiring serial communication ports
• ISDN terminal adaptors and high-speed modem interfaces
• Industrial instrumentation and uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific suffix 'IAZ-T' against official Renesas documentation to confirm package type, tape-and-reel configuration, and RoHS compliance status. Ensure the ordering code matches the exact pinout and moisture sensitivity level required for the target assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.

Selection Notes

Select this component when a single +5V supply is available instead of traditional ±12V rails. The HIN211EIAZ-T is suitable for designs requiring multiple receiver lines and four drivers within a compact SSOP footprint. Consider the low shutdown current if energy conservation is critical. Verify that the 230 kb/s data rate meets the system's communication speed requirements.

Part Context

This part belongs to the HIN2xxE family of RS-232 interface circuits designed for high-speed communications. The family includes variants like HIN206E and HIN213E, which share similar core technologies but differ in driver and receiver counts. The HIN211E specifically provides a balanced configuration for complex serial bus architectures.

Replacement Considerations

Direct functional substitutes within the same family include HIN211EIBZ-T and HIN211EIZ-T. These alternatives may differ in package style or manufacturing location but maintain identical electrical characteristics and pinouts. Verify compatibility before substitution.
