MAX3235ECPP+G36

Overview

The MAX3235ECPP+G36 is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 5 V supply and supports data rates up to 120 kbps. The device integrates charge pumps to generate the required RS-232 voltage levels, eliminating the need for external capacitors in some configurations, though typically small capacitors are used. It features two drivers and two receivers with full-duplex operation. The component includes a shutdown mode to minimize power consumption during idle periods. It is housed in a 20-pin PDIP package and is designed for industrial temperature ranges.

Feature Summary

• Integrates dual RS-232 transceivers with internal charge pumps for single-supply operation
• Includes a dedicated shutdown pin to reduce power consumption
• Provides ESD protection on all lines to safeguard connected equipment

Applications

• Industrial control systems requiring serial communication
• Point-of-sale (POS) terminals
• Medical instrumentation with serial interfaces

Procurement Notes

Verify the specific suffix G36 indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type matches the design requirements, as variations exist between SOIC and PDIP formats within the same series. Check current availability status, as this part number may be subject to discontinuation or lifecycle changes. Ensure the operating voltage range aligns with the system's 5 V supply rails.

Selection Notes

Select this component when a dual-channel RS-232 interface is needed with low standby power. Compare against the MAX3233EEWP+TG36 if 3.3 V operation is required instead of 5 V. Consider the MAX3235ECWP+TG36 if a surface-mount SOIC package is preferred over the through-hole PDIP option. Verify that the 120 kbps data rate meets the application's speed requirements.

Part Context

This part belongs to the Maxim MAX323x family of low-power RS-232 transceivers. It is functionally similar to the MAX3235E but specified for extended industrial temperature ranges. The +G36 suffix denotes environmental compliance. It serves as a bridge between microcontroller UARTs and RS-232 ports in embedded systems.

Replacement Considerations

The MAX3235ECWP+G36 is a pin-compatible surface-mount alternative. For 3.3 V systems, the MAX3233 series is suitable. Verify electrical specifications match before substitution.
