HIN208IB

Overview

The HIN208IB is a single-supply RS-232 transceiver manufactured by Harris Corporation. It operates from a single +5V power supply and integrates onboard charge pump voltage converters to generate the required ±10V supplies for RS-232 signaling, eliminating the need for external dual-voltage sources. The device features two drivers and two receivers, supporting data rates up to 120 kbit/s. It meets EIA RS-232E and V.28 specifications. Key electrical characteristics include a ±30V input voltage range for receivers, three-state TTL/CMOS compatible outputs, and low power consumption with typical values of 5mA active and 1µA in shutdown mode.

Feature Summary

• Single +5V power supply operation with integrated onboard charge pump voltage doubler and inverter
• Compliance with EIA RS-32E and V.28 interface specifications
• Low power shutdown function significantly reducing standby current consumption
• Three-state outputs with TTL/CMOS compatibility and output current limiting

Applications

• Computer serial communication ports
• Portable and laptop computer interfaces
• Peripheral connections such as printers and terminals
• Instrumentation requiring RS-232 connectivity

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm package integrity and pin alignment against original datasheet specifications before integration. Check for obsolescence status as legacy components may have limited production runs. Ensure environmental compliance documentation matches project requirements.

Selection Notes

Select this component when designing systems requiring RS-232 communication without access to negative voltage rails. It is suitable for space-constrained applications where external capacitors are limited to 0.1µF or greater. Consider thermal management for continuous high-duty cycle operations. Evaluate alternative modern equivalents if long-term supply stability is a critical constraint for the product lifecycle.

Part Context

The HIN208IB belongs to the HIN200-HIN213 family of RS-232 transmitters and receivers designed by Harris Corporation. This family addresses applications where traditional ±12V supplies are unavailable, offering a simplified power architecture. The devices share common architectural benefits, including onboard voltage conversion and low power consumption, making them standard solutions for legacy serial interface implementations in industrial and consumer electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided reference material. Designers should consult official manufacturer resources for current cross-reference lists or equivalent modern RS-232 transceivers that maintain single-supply operation and pin compatibility.
