Description and Introduction

+5V Powered RS-232 Transmitters/Receivers The **HIN231CP** from Intersil is a high-performance, dual-channel RS-232 transceiver designed for reliable serial communication in industrial and embedded applications. This integrated circuit (IC) combines robust signal conditioning with low power consumption, making it suitable for systems requiring stable data transmission over extended distances.  

Featuring ±15kV ESD protection on its transceiver pins, the HIN231CP ensures durability against electrostatic discharge, enhancing system reliability in harsh environments. Its wide operating voltage range (3V to 5.5V) allows compatibility with both 3.3V and 5V logic levels, offering flexibility in mixed-voltage designs.  

The HIN231CP supports data rates up to 120kbps, making it ideal for moderate-speed communication protocols. Its low-power shutdown mode minimizes energy consumption when inactive, a critical feature for battery-operated devices. Additionally, the IC includes an integrated charge pump, eliminating the need for external voltage converters to generate RS-232 signal levels.  

Engineers favor the HIN231CP for its compact SOIC package, ease of integration, and compliance with industry-standard RS-232 specifications. Whether used in industrial automation, point-of-sale terminals, or embedded controllers, this transceiver delivers consistent performance with minimal design complexity.  

With its balance of efficiency, protection, and versatility, the HIN231CP remains a dependable choice for serial communication solutions.

Application Scenarios & Design Considerations

+5V Powered RS-232 Transmitters/Receivers

Alternative Part Number

  • MAX231CPE --: Pin-compatible dual RS-232 driver/receiver with the same +5V single-supply operation and DIP package, widely available and a direct functional drop-in.
  • ICL231CPE --: Equivalent dual RS-232 transmitter/receiver in a 16-pin DIP, same supply and pinout family, making it a reliable second-source substitute.
  • ST232CN --: Low-cost dual RS-232 driver/receiver in DIP with comparable electrical characteristics and pinout, suitable as a budget-friendly replacement.
  • MAX231CPE+ --: Pin-compatible dual RS-232 driver/receiver in a DIP package with the same +5V/-5V charge-pump architecture, widely available and a direct functional drop-in.
