HIN211EIA

Overview

The HIN211EIA is an RS-232 transceiver from the Intersil HIN211 family, designed for high-speed data transmission up to 230 kb/s. It integrates four drivers and five receivers in a single package, supporting full-duplex communication over RS-232 interfaces. The device operates on a single +5V supply, utilizing onboard charge pumps to generate the necessary ±10V internal voltages. Key electrical specifications include a maximum supply voltage of 5.5V and a minimum of 4.5V, with a typical operating current of 20 mA. It features robust ±15kV ESD protection on I/O pins and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated onboard charge pump eliminates the need for external dual-voltage supplies by generating ±10V from a single +5V source.
• High-speed transmitter circuitry supports data rates up to 230 kb/s, suitable for ISDN and high-speed modem applications.
• Robust electrostatic discharge protection rated at ±15kV on both transmitter outputs and receiver inputs ensures signal integrity.
• Low power shutdown mode significantly reduces energy consumption, making the component suitable for battery-powered systems.

Applications

• ISDN terminal adapters and network interface units
• High-speed modem implementations requiring RS-232 connectivity
• Battery-operated portable equipment needing low-power serial communication
• Industrial control systems with multiple serial input/output channels

Procurement Notes

Verify the suffix 'IA' corresponds to the specific industrial temperature grade (-40°C to +85°C) and SSOP-28 packaging configuration. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the supplier provides traceable documentation matching the Renesas or Intersil manufacturing origin to guarantee component authenticity and performance consistency.

Selection Notes

Select this component when an application requires a high driver-to-receiver ratio (4:5) within a compact footprint. It is appropriate for designs constrained to a single +5V power rail while maintaining high-speed data transfer capabilities. Consider the integrated shutdown feature if power management is critical, and verify that the ±15kV ESD rating meets the environmental protection requirements of the target deployment site.

Part Context

The HIN211EIA belongs to the broader HIN2xxE series of RS-232 transmitters and receivers developed by Intersil, now part of Renesas Electronics. This family shares common architectural features such as single-supply operation and high ESD tolerance. The HIN211 variant specifically distinguishes itself through its multi-driver and multi-receiver configuration, offering greater interface flexibility compared to simpler single-channel counterparts like the HIN232.

Replacement Considerations

Cross-reference with the MAX211E from Texas Instruments for functional compatibility. Verify pinout alignment and electrical parameter equivalence, particularly regarding the 230 kb/s data rate and ±15kV ESD protection levels, before substituting in existing designs.
