HIN202ECBNZ-T

Overview

The HIN202ECBNZ-T is an RS-232 transceiver integrated circuit manufactured by Renesas Electronics. It features two drivers and two receivers, supporting full-duplex communication at data rates up to 230 kb/s. The device operates on a single +5V power supply (4.5V to 5.5V) with onboard charge pumps generating ±10V rails using only 0.1µF external capacitors. It provides ±15kV ESD protection on transmitter outputs and receiver inputs. Packaged in a 16-SOIC-Narrow format, it functions within a commercial temperature range of 0°C to +70°C and draws 15 mA operating current.

Feature Summary

• Integrated charge pump voltage converter requiring minimal 0.1µF external capacitance for ±10V generation from a single 5V supply
• Transmitter outputs and receiver inputs protected against ±15kV electrostatic discharge events
• Redesigned transmitter circuitry enhances data rate and slew rate performance for high-speed applications

Applications

• ISDN terminal adaptors requiring high-speed RS-232 communication
• High-speed modem interfaces
• Portable computer and laptop peripheral connections

Procurement Notes

Verify the specific suffix BNZ-T confirms the SOIC-Narrow-16 package and commercial temperature grade during acquisition. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering part number matches the required pinout and electrical specifications for the target design implementation.

Selection Notes

Select this component when ±12V supplies are unavailable and a single 5V source must generate RS-232 levels. Choose this variant over wide-package options if board space constraints require the narrower SOIC footprint. Verify that the 230 kb/s speed meets system requirements compared to slower legacy alternatives.

Part Context

This device belongs to the HIN202E family of RS-232 transceivers designed for high-speed communication where standard ±12V supplies are absent. The family includes variants with different driver/receiver counts and shutdown modes. The HIN202ECBNZ-T specifically addresses compact, low-voltage applications needing robust ESD protection and simplified external capacitor requirements.

Replacement Considerations

HIN202CBZ-T offers similar functionality but lacks ESD protection and supports lower data rates. HIN202EIBNZ-T provides industrial temperature range (-40°C to +85°C) instead of commercial range. HIN202ECP is the through-hole DIP equivalent. Verify package dimensions and thermal characteristics when substituting.
