HIN213CA

Overview

The HIN213CA is a single-supply RS-232 transceiver from the HIN2xxE family, designed for +5V operation without requiring external ±12V supplies. It integrates onboard charge pumps to generate +10V and -10V rails using only 0.1µF external capacitors. The device features two drivers and three receivers, with inputs compatible with TTL/CMOS logic. Key electrical specifications include a data rate of up to 120kbit/s (high-speed variant) or lower standard rates, ±15kV ESD protection on I/O pins, and a shutdown current of typically 1µA. The package is SSOP-28 with dimensions of 10.2 x 5.3 x 1.75 mm.

Feature Summary

• Single +5V power supply operation with integrated voltage conversion
• High electrostatic discharge protection rated at ±15kV
• Low power shutdown mode with active receiver wakeup capability
• TTL/CMOS input compatibility with slew-rate limited outputs

Applications

• Portable computers and laptop serial ports
• ISDN terminal adaptors and high-speed modems
• Printers and terminals requiring RS-232 connectivity
• Instrumentation systems with limited power availability

Procurement Notes

Verify the suffix 'CA' against official Intersil/Renesas documentation to confirm it denotes the commercial temperature range (0°C to +70°C) and SSOP package. Ensure the component is sourced from authorized distributors to guarantee RoHS compliance and lead-free status as specified in the datasheet. Cross-reference the manufacturer part number with current Renesas listings due to corporate acquisitions.

Selection Notes

Select the HIN213CA when a system requires multiple receiver channels alongside driver functionality within a single IC. This model is appropriate for battery-powered devices needing low standby current via its shutdown feature. Verify that the required data rate does not exceed the specific speed class of the E-series variant selected, and ensure PCB space accommodates the 28-pin SSOP footprint and necessary 0.1µF charge pump capacitors.

Part Context

The HIN213CA belongs to the HIN2xxE family of RS-232 interface circuits originally developed by Harris Corporation and later maintained by Intersil and Renesas. These devices were engineered to replace traditional dual-supply transceivers in modern low-voltage digital systems. The family includes variants like HIN202E and HIN232E, differentiated by the number of drivers and receivers provided.

Replacement Considerations

Publicly confirmed substitutes include the MAX213EIA+ (Maxim Integrated) and the SP3232E (Maxim Integrated). These components offer similar pinouts and functionality but may require verification of specific electrical parameters such as ESD ratings and shutdown currents against the original HIN213CA specifications.
