HIN208IA

Overview

The HIN208IA is a quad line transceiver from the HIN200-HIN213 family, designed to meet EIA RS-232E and V.28 specifications. It operates on a single +5V power supply, utilizing onboard charge pumps to generate ±10V supplies with only 0.1µF external capacitors. The device features four drivers and five receivers, supporting a data rate of 120kbit/s. Key electrical characteristics include a maximum slew rate of 30V/µs, ±30V input voltage range for receivers, and 300Ω power-off source impedance. It offers low power consumption of typically 5mA and includes a shutdown function reducing current to 1µA.

Feature Summary

• Single +5V operation with onboard charge pump generating ±10V
• Meets all EIA RS-232E and V.28 interface specifications
• Low power shutdown mode for energy conservation
• TTL/CMOS compatible inputs and outputs

Applications

• Portable computers and laptops
• Mainframe computer interfaces
• Printers and terminals
• Instrumentation systems

Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets were acquired by Renesas Electronics. Confirm the specific package type (PDSO28 or SSOP-28) matches the design requirements. Ensure the component meets RoHS standards if required for the target assembly process. Check for moisture sensitivity level compliance during storage and handling.

Selection Notes

Select this component when a quad driver/receiver configuration is needed for RS-232 communication. It is suitable for systems requiring a single +5V supply without external high-voltage generation circuits. Consider the 120kbit/s data rate limit for application compatibility. Verify that the 0.1µF external capacitor requirement fits within the board space constraints.

Part Context

The HIN208IA belongs to the HIN200-HIN213 family of RS-232 transceivers originally developed by Harris Corporation. This family was later integrated into Intersil and subsequently Renesas Electronics product lines. The device provides a complete solution for serial communication interfaces in 5V logic environments.

Replacement Considerations

Direct substitutes include other members of the HIN200-HIN213 family such as HIN208E or HIN232E, provided pinout and functional compatibility are verified. Cross-reference with Renesas or Intersil datasheets for equivalent part numbers.
