HIN232ECBZ

Overview

The HIN232ECBZ-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates from a single +5V power supply and meets EIA RS-232E and V.28 specifications. The device features onboard charge pump voltage converters that generate +10V and -10V supplies, eliminating the need for external ±12V sources. It includes two drivers and two receivers with true TTL/CMOS input compatibility. Key electrical parameters include a data rate of 230 kbit/s, ±15kV ESD protection on transmitter outputs and receiver inputs, and a typical operating current of 5 mA. The component supports an input voltage range of ±30V and offers 300Ω power-off source impedance.

Feature Summary

• Onboard charge pump generates required dual polarity voltages from a single +5V supply
• High-speed data transmission capability up to 230 kbit/s
• Robust electrostatic discharge protection rated at ±15kV
• TTL and CMOS logic input compatibility for direct interfacing

Applications

• Portable computers and laptop systems
• Mainframe computer communication ports
• Peripheral devices such as printers and terminals
• Instrumentation and UPS systems
• ISDN terminal adaptors and high-speed modems

Procurement Notes

Verify the specific suffix 'CBZ' against official Renesas documentation to confirm package type and temperature range. Ensure the ordering code matches the exact RoHS compliance status required for the project. Confirm moisture sensitivity level (MSL) ratings prior to surface mount assembly processes.

Selection Notes

Select this component when designing systems limited to a single +5V power rail without access to negative voltage supplies. It is suitable for applications requiring high noise immunity due to receiver hysteresis. Verify that the 230 kbit/s data rate aligns with the system's communication requirements and that the SOIC-16 package fits the PCB layout constraints.

Part Context

This part belongs to the HIN232-HIN241 series of RS-232 interface circuits designed for environments lacking ±12V power rails. The family provides various driver and receiver combinations to accommodate different interface needs while maintaining compliance with standard RS-232 protocols.

Replacement Considerations

Check for HIN232ACBNZ or other variants within the same HIN232E family. Verify pinout compatibility and functional equivalence before substitution.
