HIN211CB-T

Overview

The HIN211CB-T is a quad line transceiver manufactured by Harris Corporation, designed for RS-232 communication interfaces. It operates on a single +5V power supply and utilizes onboard charge pump voltage converters to generate the required ±10V supplies from the input voltage. The device meets EIA RS-232E and V.28 specifications, featuring four drivers and five receivers. It supports data rates up to 120kbit/s with a maximum slew rate of 30V/µs. The receivers offer a ±30V input voltage range and include 0.5V hysteresis for improved noise rejection. The package is identified as PDSO28.

Feature Summary

• Onboard charge pump voltage converters generate internal ±10V supplies from a single +5V source.
• TTL/CMOS compatible outputs with three-state receiver functionality.
• High noise rejection capability provided by receiver input hysteresis.
• Output current limiting and low power-off source impedance protection.

Applications

• Computer serial communication ports
• Portable and laptop computer interfaces
• Peripheral connections such as printers and terminals

Procurement Notes

Verify the manufacturer designation carefully, as the component was originally produced by Harris Corporation and later acquired by Intersil, which became part of Renesas Electronics. Confirm that the specific suffix 'CB-T' corresponds to the tape and reel packaging format intended for automated assembly processes. Ensure the device version aligns with RoHS compliance requirements if applicable to the target system.

Selection Notes

Select this component when a single +5V supply is available but standard RS-232 voltage levels are required without external high-voltage generators. It is suitable for applications needing multiple transmitter and receiver channels in a compact surface-mount package. Consider the 120kbit/s data rate limit and ensure it meets the timing requirements of the specific serial interface protocol being implemented.

Part Context

The HIN211 belongs to a family of RS-232 transmitters and receivers that includes variants like the HIN202, HIN206, and HIN213. These devices share common architecture features such as onboard charge pumps and single-supply operation. The HIN211 specifically provides a configuration with four drivers and five receivers, distinguishing it from other members of the series that may offer different driver-to-receiver ratios.

Replacement Considerations

Compatible substitutes within the same family include the HIN211CBZ-T and HIN211IA. Verify pin compatibility and electrical specifications before substitution. Note that the manufacturer lineage has transitioned from Harris to Intersil and subsequently to Renesas Electronics.
