HIN208ECBZ

Overview

The HIN208ECBZ is a dual driver/receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates on a single +5V supply, utilizing onboard charge pumps to generate the required ±10V levels from external 0.1µF capacitors. The device meets EIA high-speed RS-232E and V.28 specifications with a data rate of 230kbps. It features ±15kV ESD protection on I/O pins and receiver hysteresis for noise rejection. Packaged in a 16-SOIC (0.295", 7.50mm width) surface-mount format, it supports an operating temperature range of 0°C to 70°C.

Feature Summary

• Onboard charge pump voltage conversion eliminates need for external ±12V supplies
• High ESD protection rated at ±15kV on transmitter outputs and receiver inputs
• Receiver input hysteresis enhances noise immunity in electrically noisy environments

Applications

• Portable computers and laptop peripheral interfaces
• ISDN terminal adaptors and high-speed modem connections
• Instrumentation and UPS serial communication ports

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package marking matches the 16-SOIC form factor and check date codes against current production status. Ensure environmental compliance documentation aligns with project requirements prior to final procurement authorization.

Selection Notes

Select this component when a dual-channel RS-232 interface is required within a single +5V system architecture. It is suitable for designs needing moderate data rates up to 230kbps without complex power management circuitry. Consider thermal dissipation limits and PCB layout constraints associated with SOIC-16 packages during integration planning.

Part Context

This part belongs to the HIN202E/HIN206E/HIN208E family of RS-232 transceivers designed for applications where traditional ±12V power rails are unavailable. The family shares common architectural features including TTL/CMOS compatibility and slew-rate limited outputs, differing primarily in the number of drivers and receivers provided per package.

Replacement Considerations

Compatible alternatives include the HIN202E, HIN206E, and HIN211E series devices from Renesas. Verify pinout compatibility and functional equivalence regarding driver/receiver counts before substitution. Cross-reference specific suffixes for package variations and temperature ranges.
