HIN232ACBNZ-T

Overview

The HIN232ACBNZ-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics. It meets EIA RS-232E and V.28 specifications, operating on a single +5V power supply with onboard charge pumps generating ±10V. The device features two drivers and two receivers, supporting data rates up to 230 kbit/s. It utilizes a 16-pin SOIC-Narrow package with a 1.3 mm pitch. Key electrical parameters include a typical supply current of 5 mA, an input voltage range of ±30V for receivers, and a power-off source impedance of 300Ω. The operational temperature range spans from 0°C to +70°C.

Feature Summary

• Onboard voltage doubler and inverter generate required ±10V supplies from a single +5V source, eliminating the need for external dual-voltage rails.
• Integrated hysteresis on receiver inputs significantly improves noise rejection capabilities in electrically noisy environments.
• Drivers provide true TTL/CMOS input compatibility alongside slew-rate-limited outputs to minimize electromagnetic interference.
• Outputs maintain a 300Ω source impedance when powered off, ensuring safe bus sharing in multi-driver configurations.

Applications

• High-speed RS-232 communication ports in portable computers and laptops
• Peripheral connections for printers and terminals
• Instrumentation systems and uninterruptible power supplies (UPS)
• Modems and ISDN terminal adaptors

Procurement Notes

Verify the specific suffix 'CBNZ' against official Renesas documentation to confirm package type and RoHS compliance status. Ensure the ordering code matches the exact pinout and electrical characteristics required for the design. Cross-reference the manufacturer's latest datasheet to confirm availability and any potential lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component for designs requiring high-speed RS-232 communication without access to ±12V power rails. The integrated charge pump reduces external component count compared to older generations. Verify that the 230 kbit/s data rate aligns with system requirements and that the SOIC-16 package fits the PCB layout constraints.

Part Context

This part belongs to the HIN232-HIN241 series of high-speed RS-232 transmitters and receivers. The series is designed for applications where standard ±12V supplies are unavailable, relying instead on a single +5V logic supply. The HIN232 variant specifically provides a balanced configuration of two drivers and two receivers within the family.
