HIN213IB

Overview

The HIN213IB is a single-supply RS-232 transceiver manufactured by Harris Corporation. It operates from a single +5V power supply and utilizes onboard charge pumps to generate the required ±10V internal voltages, eliminating the need for external dual supplies. The device integrates two receivers and three drivers, meeting EIA RS-232E and V.28 specifications. Key electrical characteristics include a data rate of 120 kbit/s, a typical quiescent current of 5 mA, and a shutdown current of 1 µA. The receivers feature 0.5V hysteresis for noise rejection and operate with a ±30V input voltage range.

Feature Summary

• Integrates onboard charge pump voltage converters to generate positive and negative supplies from a single +5V source
• Provides two active receivers in shutdown mode to maintain communication capability during low-power states
• Features TTL/CMOS compatible outputs with three-state logic and output current limiting protection

Applications

• Portable computers and laptop systems requiring RS-232 connectivity
• Mainframe computer peripheral interfaces
• Industrial printers and terminals

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that Harris Semiconductor assets were acquired by Intersil and subsequently Renesas. Confirm the specific suffix 'IB' denotes the industrial temperature grade and package variant. Request official datasheets to validate pinout compatibility and electrical parameters against original specifications before integration.

Selection Notes

Select this component when a single +5V supply is available but RS-232 signal levels are required without external high-voltage generation circuits. It is suitable for designs prioritizing board space savings due to the integrated charge pump. Ensure the application requires two receivers and three drivers, and verify that the 120 kbit/s data rate meets system timing requirements.

Part Context

The HIN213IB belongs to the HIN200-HIN213 family of RS-232 interface circuits designed for applications where ±12V supplies are unavailable. This family offers various transmitter/receiver combinations tailored for different pin counts and functional needs. The HIN213 specifically provides a balanced configuration of two receivers and three drivers within a compact footprint.
