MAX3235ECWP

Overview

The MAX3235ECWP is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-SOIC surface-mount package. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 250kbps. The device features two drivers and two receivers for full-duplex communication. Key electrical specifications include a receiver hysteresis of 500 mV and a propagation delay of 0.15 µs. It provides 15 kV ESD protection on all pins and includes internal charge pumps to eliminate the need for external capacitors. The component is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates dual RS-232 drivers and receivers with internal charge pumps for simplified design
• Provides robust 15 kV ESD protection across all signal pins
• Supports standard RS-232 protocols with full-duplex transmission capabilities

Applications

• Industrial control systems requiring reliable serial communication
• Portable instrumentation and battery-powered devices
• Modem and fax machine interface circuits

Procurement Notes

Verify current availability status as the MAX3235ECWP+G36 variant is listed as obsolete in public records. Confirm RoHS compliance through official documentation before procurement. Check for valid replacement options if original stock is unavailable. Ensure the specific suffix matches project requirements.

Selection Notes

Select this component for applications requiring dual-channel RS-232 connectivity without external capacitors. Verify that the 4.5V to 5.5V supply range aligns with system power rails. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate thermal performance within the specified 0°C to 70°C operating range.

Part Context

This part belongs to the MAX3235E series of dual RS-232 transceivers. It shares functional similarities with other Maxim Integrated interface ICs but is distinct in its pinout and capacitor-less architecture. The product line focuses on low-power, high-reliability serial communication solutions for embedded systems.

Replacement Considerations

Public records indicate the MAX3235ECWP+G36 variant is obsolete. Consult official manufacturer documentation for verified substitute part numbers. Do not assume cross-compatibility with similar interface ICs without verifying pinouts and electrical parameters.
