MAX238CNG

Overview

The MAX238CNG+ is a quad driver/receiver RS-232 transceiver designed for single-supply operation. It operates from a +5V power source and supports data rates up to 120 kb/s with full-duplex communication. The device integrates four drivers and four receivers within a 24-pin PDIP package, suitable for through-hole mounting. It functions within an operating temperature range of 0°C to +70°C and draws approximately 15 mA of supply current. The component lacks ESD protection features and does not include a shutdown mode.

Feature Summary

• Provides four independent drivers and four receivers for simultaneous bidirectional serial communication
• Operates directly from a single +5V power supply without requiring external voltage inversion circuits
• Supports standard RS-232 signal levels compliant with EIA/TIA-232-E specifications

Applications

• Industrial control systems requiring robust serial communication interfaces
• Embedded devices utilizing microcontrollers with UART ports
• Data acquisition equipment needing reliable RS-232 connectivity

Procurement Notes

Verify the specific suffix designation when ordering, as packaging and material compliance may vary between variants such as CNG and CWG. Confirm availability status due to potential supply constraints associated with legacy interface components. Ensure the selected package type matches the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a quad channel RS-232 solution is required for through-hole assembly. Consider alternative packages like SOIC if surface mount technology is preferred for the design. Evaluate thermal management needs as the device operates within a standard commercial temperature range without active cooling provisions.

Part Context

This part belongs to the MAX238 family of RS-232 transceivers manufactured by Analog Devices under the Maxim Integrated brand. The series provides standardized serial communication capabilities for various electronic applications. The MAX238CNG specifically denotes the plastic dual in-line package variant within this product line.

Replacement Considerations

Direct pin-compatible substitutes include other quad RS-232 transceivers from the same manufacturer family. Verify electrical parameters and package dimensions before integrating any cross-brand alternatives into existing designs.
