HIN232ECPZ

Overview

The HIN232ECPZ is a dual transmitter and receiver RS-232 interface circuit manufactured by Renesas Electronics Corporation. It operates from a single +5V power supply and utilizes onboard charge pump voltage converters to generate the necessary positive and negative voltages for RS-232 signaling, eliminating the need for external ±12V supplies. The device meets EIA high-speed RS-232E and V.28 specifications. Key electrical parameters include a data rate of 120kbps, an operating temperature range of 0°C to +70°C, and ±15kV electrostatic discharge (ESD) protection on both transmitter outputs and receiver inputs. It is housed in a 16-pin PDIP package.

Feature Summary

• Integrated charge pump voltage converter generates internal supply rails from a single +5V source
• Transmitter outputs and receiver inputs feature ±15kV electrostatic discharge protection
• Drivers provide true TTL/CMOS input compatibility with slew-rate-limited outputs
• Receivers handle up to ±30V input voltage with hysteresis for improved noise rejection

Applications

• High-speed modems and ISDN terminal adaptors
• Portable computers, laptops, and mainframes
• Peripheral connections including printers and terminals
• Instrumentation and uninterruptible power supply (UPS) systems

Procurement Notes

Verify the specific suffix 'CPZ' against the manufacturer's current datasheet to confirm the package type and lead-free status. Ensure the component matches the required operating temperature range and pinout configuration for your design. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a single +5V supply is available but ±12V rails are not. It is suitable for applications requiring moderate data rates up to 120kbps with robust ESD protection. Compare against other family members like the HIN232A if higher data rates or different packaging options are needed. Verify that the 16-pin PDIP form factor fits the target PCB layout constraints.

Part Context

The HIN232ECPZ belongs to the HIN232E family of RS-232 transmitters and receivers. This family includes variants such as the HIN202E, HIN206E, HIN211E, and HIN213E, which offer different combinations of drivers and receivers. The HIN232E specifically provides two transmitters and two receivers, making it a full-duplex solution for standard RS-232 communication links.

Replacement Considerations

Direct replacements within the same family include the HIN232ACBNZ (SOIC package) or HIN232ECBZ (SOIC-Wide package). Other compatible devices may include the HIN232A series, though data rate specifications should be verified. Ensure any substitute maintains the 16-pin PDIP footprint and +5V operation.
