HIN232ACBZ-T

Overview

The HIN232ACBZ-T is a high-speed RS-232 transceiver manufactured by Renesas Electronics Corporation. It meets EIA RS-232E and V.28 specifications, designed for systems lacking ±12V power supplies. The device operates on a single +5V supply using onboard charge pumps to generate required voltage levels. It features one driver and two receivers with a data rate of 230 kbit/s. The component is housed in a 16-pin SOIC package (SOICN) with a 1.3 mm pitch. It functions within a temperature range of 0°C to +70°C and requires external capacitors of 0.1 µF or greater.

Feature Summary

• Onboard voltage doubler and inverter generate necessary supply rails from a single +5V source
• TTL/CMOS compatible inputs with slew-rate-limited outputs for signal integrity
• High noise rejection capability through receiver hysteresis
• Power-off state maintains 300Ω source impedance to prevent bus contention

Applications

• Portable computers and laptop serial ports
• Mainframe computer communication interfaces
• Peripheral connections including printers and terminals
• Instrumentation and UPS monitoring systems
• Modem and ISDN terminal adaptor circuits

Procurement Notes

Verify the specific suffix 'CBZ' against official Renesas documentation to confirm the exact package variant and tape-and-reel configuration. Ensure the ordering information matches the intended manufacturing revision. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 voltage levels are required. It is suitable for applications needing moderate speed up to 230 kbit/s without complex external power generation. Consider the industrial temperature range if operation exceeds commercial limits. Verify that the 16-pin SOIC footprint aligns with the target PCB layout constraints.

Part Context

This part belongs to the HIN232-HIN241 series of RS-232 interface circuits. The family provides various transmitter/receiver combinations tailored for different port configurations. The HIN232 variant specifically offers one driver and two receivers, balancing pin count with functionality for standard dual-port or single-port extended applications.

Replacement Considerations

Direct functional substitutes include other members of the HIN232 family such as HIN232ACBNZ or HIN232ECBZ-T. Verify pin compatibility and electrical parameters before substitution. Alternative packages like SSOP may require adapter solutions unless pin-compatible.
