Overview
The HIN237IBR4327 is a dual RS-232 transceiver manufactured by Intersil, designed for low-power applications. It operates from a single 3V to 5.5V supply and incorporates internal charge pumps to generate the necessary positive and negative voltages for RS-232 communication without requiring external components. The device features three receivers with 30kΩ input resistors for noise immunity and two drivers capable of driving standard loads. It supports data rates up to 120kbps and is available in an 8-pin SOIC package.
Feature Summary
- Integrated charge pump eliminates need for external capacitors
- Single-supply operation from 3V to 5.5V
- High noise immunity with 30kΩ receiver input resistors
Applications
- Portable battery-powered equipment
- Modems and fax machines
- PDAs and palmtop computers
Procurement Notes
Verify the specific suffix 'BR4327' against official Intersil or Renesas documentation to confirm exact tape-and-reel packaging specifications and lot traceability requirements. Ensure compatibility with RoHS directives if applicable to your region. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times.
Selection Notes
Select this component when designing systems requiring RS-232 connectivity with minimal external bill of materials. It is suitable for space-constrained designs where external charge pump capacitors cannot be accommodated. Verify that the required data rate does not exceed 120kbps and that the operating voltage range aligns with the system's power supply rails.
Part Context
This part belongs to the Intersil (now Renesas) HIN232 family of RS-232 transceivers. These devices are widely used in industrial and commercial applications requiring reliable serial communication. The HIN237 variant specifically offers dual drivers and receivers, providing flexibility for bidirectional communication links in compact form factors.
Replacement Considerations
Compatible replacements include the MAX237EPE from Maxim Integrated and the SP3232EEN from MaxLinear. When substituting, verify pinout compatibility and ensure that the replacement device meets the same voltage and temperature specifications.
