HIN232ECAZ-T

Overview

The HIN232ECAZ-T is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Renesas Electronics Corporation. It meets EIA RS-232E and V.28 specifications, designed for applications lacking ±12V power supplies. The device operates on a single +5V supply, utilizing onboard charge pump converters to generate internal voltage levels. It features a data rate of 230 kbit/s and includes ±15kV ESD protection on I/O pins. The component is housed in a 16-pin SSOP package with a pitch of 0.7 mm. It supports full-duplex communication with one driver and one receiver, operating within a temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump eliminates the need for external dual-voltage power supplies
• High electrostatic discharge protection ensures robust signal integrity
• TTL/CMOS compatible inputs simplify logic interfacing

Applications

• Portable computer serial port expansion
• Laptop and mainframe peripheral connections
• Industrial instrumentation and UPS systems
• ISDN terminal adaptors and high-speed modems

Procurement Notes

Verify the specific suffix 'CAZ' against official Renesas documentation to confirm package type and RoHS compliance status. Ensure the ordering quantity aligns with distributor minimums, as packaging formats may vary between tubes and reels depending on the supplier. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before finalizing procurement.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 voltage levels are required. It is suitable for designs needing moderate data rates up to 230 kbit/s with integrated noise rejection. Consider the SSOP package constraints for PCB layout. Verify that the thermal performance and input impedance requirements match the system's noise environment and power budget constraints.

Part Context

This part belongs to the HIN232E family of RS-232 transceivers from Renesas. The family shares common architecture but varies in driver/receiver counts and shutdown modes. The HIN232E variant specifically provides a single driver and receiver configuration. Other family members like HIN202E or HIN213E offer different pinouts or low-power features. This model focuses on standard high-speed communication without specialized shutdown capabilities found in other series members.

Replacement Considerations

Direct substitutes include HIN232ACBNZ or HIN232ECBZ-T, which share similar electrical characteristics and pinouts. Verify package compatibility (SSOP vs SOIC) and ensure the replacement maintains the same data rate and ESD protection levels. Check for any differences in recommended external capacitor values for the charge pump circuit.
