MAX237CNG+

Overview

The MAX237CNG+ is a +5V-powered, multichannel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features five drivers and three receivers, supporting full-duplex communication at data rates up to 120 kb/s. The device operates within a supply voltage range of 4.75V to 5.25V and consumes approximately 15 mA of operating current. It is housed in a 24-pin Narrow PDIP package designed for through-hole mounting. The component functions reliably across an extended industrial temperature range from -40°C to +85°C. It lacks shutdown functionality and integrated ESD protection.

Feature Summary

• Multichannel architecture providing five independent drivers and three receivers for complex serial communication systems.
• Capable of full-duplex data transmission with a maximum signaling rate of 120 kb/s.
• Operates on a single +5V power supply, simplifying power management in standard logic environments.

Applications

• Industrial control systems requiring robust RS-232 connectivity.
• Multi-drop serial communication networks utilizing multiple transceivers.
• Embedded systems interfacing with legacy RS-232 peripherals.

Procurement Notes

Verify the specific suffix 'CNG+' against the manufacturer's latest datasheet to confirm pinout compatibility and environmental compliance. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the procurement source provides valid traceability documentation for the Analog Devices/Maxim Integrated brand.

Selection Notes

Select this component when a design requires five driver outputs and three receiver inputs within a single IC package. It is suitable for applications needing full-duplex operation without the need for low-power shutdown modes. Verify that the system environment remains within the specified -40°C to +85°C temperature range and that the 24-pin PDIP footprint fits the PCB layout constraints.

Part Context

This part belongs to the MAX237 series of RS-232 interface integrated circuits. It is functionally equivalent to the ADM237LANZ, which shares similar electrical characteristics and pin configurations. The device represents a standard solution for multi-channel serial communication in industrial and commercial electronics.

Replacement Considerations

The ADM237LANZ is a confirmed functional substitute with identical electrical specifications and pinout. Designers should verify mechanical tolerance differences between the Maxim and Analog Devices versions before finalizing the PCB assembly.
