MAX233EPP+G36

Overview

The MAX233EPP+G36 is a dual RS-232 transceiver in a 20-pin PDIP package. It operates from a single +5V supply (4.75V to 5.25V) and includes internal charge pumps generating ±10V, eliminating external capacitors. It provides full duplex communication with two drivers and two receivers at data rates up to 120kbps. The device features a shutdown mode consuming 5μW and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external capacitors or bipolar supplies
• Enables single +5V supply operation for simplified power design
• Shutdown mode reduces power consumption to 5μW for energy efficiency

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 network connections
• Portable diagnostics equipment requiring low power and compact size

Procurement Notes

Verify the component status as discontinued based on distributor records. Confirm the specific suffix G36 indicates lead-free compliance and RoHS adherence. Ensure the PDIP package matches the required through-hole mounting constraints for the target assembly process.

Selection Notes

Select this part when board space is critical due to the absence of external capacitors. Choose the E variant for industrial temperature ranges (-40°C to +85°C). Verify that the 120kbps data rate meets system requirements and that a single +5V supply is available.

Part Context

This component belongs to the MAX220–MAX249 family of +5V-powered multichannel RS-232 drivers and receivers. The MAX233 specifically integrates capacitors internally, distinguishing it from variants like the MAX232 which require external components. It is designed for applications where ±12V supplies are unavailable.
