HIN213CB

Overview

The HIN213CB is a dual transmitter and dual receiver RS-232 interface circuit manufactured by Harris Corporation. It operates from a single +5V power supply, utilizing onboard charge pumps to generate the required ±10V levels for RS-232 signaling. The device meets EIA RS-232E and V.28 specifications with a typical data rate of 120kbit/s. It features ±15kV ESD protection on I/O pins, low power consumption (typical 5mA active, 1µA shutdown), and two receivers that remain active in shutdown mode for wakeup capability. External capacitors of 0.1µF or greater are sufficient for operation.

Feature Summary

• Single +5V power supply operation with integrated voltage conversion
• High-speed data transmission compatible with ISDN standards
• Robust electrostatic discharge protection on input and output pins
• Low power shutdown functionality with active receiver wakeup

Applications

• Portable computers and laptop serial ports
• Mainframe computer peripheral connections
• Printers and terminals requiring RS-232 communication
• Instrumentation systems with serial interfaces

Procurement Notes

Verify the manufacturer origin, as Intersil acquired Harris Semiconductor assets. Confirm RoHS compliance status and package type availability. Check for equivalent part numbers from Renesas if Harris-branded units are discontinued. Ensure the specific suffix matches the required temperature range and packaging format.

Selection Notes

Select this component when a single +5V supply is available but traditional ±12V RS-232 levels are needed. The HIN213CB is suitable for applications requiring high-speed data rates up to 120kbit/s. Consider the shutdown mode with active receivers if battery life is critical and remote wakeup is required. Verify external capacitor requirements match the design constraints.

Part Context

The HIN213CB belongs to the HIN2xxxE family of RS-232 transceivers designed for high-speed communication. This family eliminates the need for external negative voltage supplies by integrating charge pumps. The HIN213 variant specifically provides two drivers and two receivers, making it a standard choice for full-duplex serial communication in portable and industrial equipment.

Replacement Considerations

HIN232CB is a pin-compatible alternative within the same family offering similar functionality. Intersil or Renesas equivalents should be verified for electrical compatibility.
