HIN202EIBNZ-T7A

Overview

The HIN202EIBNZ-T7A is an RS-232 transceiver integrated circuit manufactured by Renesas Electronics. It complies with EIA high-speed RS-232E and V.28 specifications, designed for systems requiring high-speed serial communication without ±12V power supplies. The device integrates two drivers and two receivers, supporting data rates up to 230 kbps. It operates on a single +5V supply (4.5V to 5.5V) using onboard charge pumps to generate internal voltage levels. Key electrical parameters include ±15kV ESD protection on I/O pins, a typical operating current of 5mA, and propagation delay of 4000 ns. It functions within a temperature range of -40°C to +85°C and utilizes a 16-SOIC package.

Feature Summary

• Integrated charge pump voltage converter eliminates the need for external ±12V power rails.
• High-speed transmitter circuitry supports data rates up to 230 kbps for ISDN and modem applications.
• Robust electrostatic discharge protection rated at ±15kV on driver outputs and receiver inputs.
• Low-power shutdown mode significantly reduces standby current consumption.

Applications

• ISDN terminal adaptors and communication equipment
• High-speed modem interfaces
• Portable computers and laptop peripherals
• Industrial instrumentation and UPS systems

Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm reel packaging quantities and tape-and-reel specifications. Ensure the component matches the exact RoHS compliance status and humidity sensitivity classification required for your assembly process. Cross-reference the manufacturer date code and lot traceability requirements with your quality assurance standards before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require full-duplex RS-232 communication but are constrained to a single 5V power source. It is suitable for replacing legacy transceivers requiring dual voltages. Verify that the 230 kbps speed meets your application's baud rate needs and that the 16-pin SOIC footprint fits your PCB layout constraints. Consider the low-power shutdown feature if battery efficiency is a priority.

Part Context

This part belongs to the HIN202E family of RS-232 transceivers from Renesas (formerly Intersil). The family shares common architecture features such as the onboard charge pump and ESD protection. Variations within the family typically differ in driver/receiver counts or additional features like active wake-up during shutdown. This specific model represents the standard 2-driver/2-receiver configuration optimized for general-purpose high-speed serial links.

Replacement Considerations

Direct replacements include other members of the HIN202E family, such as the HIN202EIBZ-T, provided pin compatibility and package dimensions match. Verify that substitute parts maintain the same 230 kbps data rate and ±15kV ESD rating. Ensure any alternative ICs support the same 5V-only operation and offer comparable propagation delay characteristics for signal integrity.
