HIN232ACB-T

Overview

The HIN232ACB-T is a high-speed RS-232 transmitter/receiver interface circuit manufactured by Renesas Electronics. It meets EIA RS-232E and V.28 specifications, operating on a single +5V power supply with onboard charge pump converters generating ±10V. The device features a data rate of 230 kbit/s, 3 drivers, and 3 receivers. It includes ±15kV ESD protection on I/O pins, 0.5V receiver hysteresis for noise rejection, and 300Ω power-off source impedance. Operating temperature range is 0°C to +70°C.

Feature Summary

• High-speed data transmission capability up to 230 kbit/s suitable for ISDN and modem applications
• Integrated ±15kV electrostatic discharge (ESD) protection on all RS-232 input and output pins
• Single +5V power supply operation utilizing onboard voltage doubler and inverter circuits
• Enhanced noise immunity through receiver input hysteresis and TTL/CMOS compatible inputs

Applications

• High-speed RS-232 communications ports in computer systems
• ISDN terminal adaptors and high-speed modems
• Peripheral connections including printers and terminals
• Instrumentation and UPS systems requiring robust serial interfaces

Procurement Notes

Verify the specific suffix 'CB-T' against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure the component matches the required industrial or commercial temperature grade. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and RoHS compliance details before procurement.

Selection Notes

Select this component when designing systems that require high-speed RS-232 communication without access to dual ±12V power supplies. It is appropriate for applications needing multiple driver and receiver channels within a single package. Consider the 0.5V hysteresis feature for environments with significant electrical noise. Verify that the external capacitor requirements align with the board space constraints.

Part Context

The HIN232ACB-T belongs to the HIN232E family of RS-232 transceivers from Renesas. This family is designed to replace traditional dual-supply solutions by integrating charge pumps on a single +5V rail. The device shares core architectural features with other members like the HIN232A but includes enhanced ESD protection characteristics typical of the 'E' series variants.

Replacement Considerations

Direct replacements include the HIN232ACBNZ for leaded SOIC packages or the HIN232ACBZ for similar surface-mount configurations. Verify pin compatibility and electrical parameters against the original design requirements when substituting.
