HIN208ECAZ-T

Overview

The HIN208ECAZ-T is an RS-232 transceiver manufactured by Renesas Electronics Corporation, belonging to the HIN20xE family. It operates on a single +5V power supply and features onboard charge pumps generating ±10V for signal levels. The device includes two drivers and two receivers with full-duplex communication capability. Key electrical parameters include a data rate of 120 kb/s, propagation delay of 0.4 µs, and shutdown current of 1 µA. It supports voltage ranges from 4.5V to 5.5V and operates within a temperature range of -40°C to +85°C. The component provides ±15kV ESD protection on I/O pins and utilizes an SSOP-20 package.

Feature Summary

• Integrated onboard charge pump eliminates need for external dual-voltage supplies
• High electrostatic discharge protection on transmitter outputs and receiver inputs
• Low power shutdown mode significantly reduces current consumption
• TTL/CMOS compatible inputs and outputs for direct microcontroller interfacing

Applications

• Portable computers and laptop serial ports
• Industrial instrumentation requiring robust RS-232 links
• Battery-powered equipment needing low standby current
• Modems and ISDN terminal adaptors

Procurement Notes

Verify the specific suffix 'ECAZ-T' against official Renesas documentation to confirm pinout compatibility and moisture sensitivity level. Ensure ordering aligns with the manufacturer's current production status, as legacy interface components may undergo lifecycle changes. Cross-reference the RoHS compliance status with the latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select this component when a single +5V supply is available but RS-232 voltage levels are required. It is suitable for designs prioritizing low power consumption in active modes due to the shutdown feature. Compare driver/receiver counts against system requirements; this part offers two of each. Verify that the 120 kb/s data rate meets application speed needs compared to higher-speed alternatives in the same family.

Part Context

This part belongs to the HIN20xE series of high-speed RS-232 transmitters and receivers. The series is designed to replace traditional dual-supply solutions by integrating voltage converters on-chip. It shares architectural similarities with other members like the HIN202E and HIN213E, differing primarily in the number of drivers and receivers provided per package.

Replacement Considerations

Direct functional substitutes within the same family include the HIN208E (non-Z version) or HIN208EC. Check for updated suffixes indicating lead-free or RoHS-compliant variants. Verify package dimensions match the existing PCB footprint if replacing older non-Z versions.
