MAX252BCHL

Overview

The MAX252BCHL is a complete, +5V-powered, isolated dual RS-232 transceiver module manufactured by Maxim Integrated. It integrates two drivers and two receivers within a single PDIP-40 plastic module package. The device complies with EIA-232-D and V.28 interface standards and features Schmitt trigger inputs for noise immunity. Designed for less stringent applications, it provides an isolated data interface solution. The component operates with a single function count and lacks differential outputs.

Feature Summary

• Integrated isolation barrier for the dual RS-232 transceiver module
• Schmitt trigger input characteristics for signal integrity
• Single +5V power supply operation capability

Applications

• Isolated data interface systems
• Less stringent industrial communication applications

Procurement Notes

Verify lead times and authenticity through authorized distributors. Confirm RoHS compliance status as the part may be non-compliant. Check for the -T suffix variant if tape-and-reel packaging is required instead of the standard DIP module form factor.

Selection Notes

Select this module when a pre-assembled isolated RS-232 solution is needed to simplify board layout. Ensure the application does not require high-speed or stringent isolation specifications. Verify that the PDIP-40 footprint fits the target enclosure constraints.

Part Context

This component belongs to the Maxim Integrated line of isolated interface modules. It serves as a compact alternative to discrete RS-232 designs requiring external isolation components. The module consolidates driver, receiver, and isolation technology into one unit.

Replacement Considerations

Check for the MAX252BCHL-T variant if reel packaging is preferred. No direct cross-model substitutes are confirmed in public documentation.
