HIN208ECBZ-T

Overview

The HIN208ECBZ-T is a high-speed RS-232 transceiver from the Renesas HIN20xE family, designed for applications requiring ±15kV ESD protection and operation from a single +5V supply. It integrates onboard charge pumps to generate internal ±10V supplies, eliminating the need for external dual-voltage sources. The device features two drivers and two receivers with true TTL/CMOS input compatibility and slew-rate-limited outputs. Key electrical parameters include a data rate of 230 kbps, a supply voltage range of 4.5V to 5.5V, and an operating temperature range of -40°C to +85°C. It is housed in a 16-pin SOIC-N package.

Feature Summary

• Integrated charge pump circuitry generates internal positive and negative voltages from a single 5V source.
• Transmitter outputs and receiver inputs are protected against electrostatic discharge up to ±15kV.
• Receivers incorporate hysteresis to significantly improve noise rejection capabilities.
• Drivers feature 300Ω power-off source impedance to prevent bus contention during power loss.

Applications

• Portable computers, laptops, and mainframes
• High-speed modems and ISDN terminal adaptors
• Printers, terminals, and peripheral devices
• Instrumentation and UPS systems

Procurement Notes

Verify the specific suffix 'CBZ-T' against official Renesas documentation to confirm the tape-and-reel packaging format and lead-free status. Ensure the component meets RoHS requirements if applicable to your manufacturing process. Cross-reference the datasheet revision date to confirm current specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require robust ESD protection and reliable RS-232 communication without access to negative voltage rails. The HIN208E variant provides two drivers and two receivers, making it suitable for full-duplex applications. Consider the -40°C to +85°C industrial temperature range for broader environmental compatibility compared to commercial grade options.

Part Context

This part belongs to the HIN20xE series of RS-232 transmitters and receivers, which meet EIA high-speed RS-232E and V.28 specifications. The family includes variants like HIN202E, HIN211E, and HIN213E, offering different combinations of drivers and receivers. The HIN208E specifically addresses needs for balanced driver/receiver counts in compact designs.

Replacement Considerations

Direct pin-compatible substitutes within the same family include HIN208EIBZ or HIN208ECZ. Verify that alternative packages (e.g., DIP vs. SOIC) match the PCB footprint. Ensure any replacement maintains the same ESD protection levels and single-supply charge pump functionality.
