MAX3233EEPP+G36

Overview

The MAX3233EEPP+G36 is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3 V to 5.5 V supply and features internal charge pumps, eliminating the need for external capacitors. The device provides two drivers and two receivers with full-duplex communication capability at data rates up to 250 kbps. It includes a shutdown mode for low power consumption and offers 15 kV ESD protection on RS-232 lines. The component is housed in a 20-pin PDIP package and supports operation over an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump design removes requirement for external flying capacitors
• High electrostatic discharge protection rating on signal interfaces
• Low current consumption with dedicated power-down control

Applications

• Industrial serial communication equipment
• Portable battery-powered instruments
• Modems and fax machines
• Point-of-sale terminals

Procurement Notes

Verify the specific suffix G36 indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the PP suffix corresponds to the 20-pin plastic DIP package type. Check obsolescence notices or last-time buy dates, as older Maxim products may have limited availability or end-of-life status. Ensure sourcing channels provide valid traceability for industrial grade components.

Selection Notes

Select this part when a dual-channel RS-232 interface is required with minimal external component count. The 3V to 5.5V operating range makes it suitable for both 3.3V and 5V logic systems. Compare against the MAX3232 if only one driver/receiver pair is needed, or the MAX3235 if higher drive current is necessary. Verify that the through-hole PDIP package fits the target PCB layout constraints.

Part Context

This component belongs to the MAX323xE family of low-power RS-232 transceivers. It shares functional similarities with the MAX3232 and MAX3235 but differs in pin count and channel configuration. The EE variant typically denotes extended temperature performance and enhanced ESD protection compared to standard commercial grades. It serves as a legacy interface solution for modern microcontrollers requiring serial connectivity.

Replacement Considerations

Direct pin-compatible alternatives include the MAX3232EEPP+G36 for single-channel applications or the MAX3235EEPP+G36 for higher drive strength. Cross-reference with newer generations like the MAX3232/MAX3233 series if updated packaging or supply chain stability is required. Verify electrical parameters match before substitution.
