MAX207ECNG

Drivers, Receivers, Transceivers Overview

The MAX207ECNG is a single-supply RS-232 transceiver from the MAX202E–MAX213E family, manufactured by Analog Devices Inc./Maxim Integrated. It features five drivers and three receivers, supporting data rates up to 120kbps. The device operates on a single +5V supply (4.75V to 5.25V) utilizing an integrated charge pump to generate ±10V internal rails, eliminating the need for external bipolar supplies. It requires four external 0.1μF capacitors for the charge pump circuitry. The component provides ±15kV ESD protection on driver outputs and receiver inputs per the Human Body Model. It is housed in a 24-pin SSOP package and supports an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single +5V supply operation without requiring external bipolar voltage sources.
• High electrostatic discharge protection rated at ±15kV on RS-32 driver outputs and receiver inputs.
• Five independent drivers and three receivers provide flexible interface configurations for complex serial communication systems.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption and single-supply compatibility.
• Hand-held devices where board space savings are critical due to the compact SSOP packaging.
• Portable diagnostic equipment operating in harsh environments with frequent connection changes.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'CNG' against official manufacturer documentation to confirm pinout and package dimensions. Confirm that the 'E' designation aligns with the required ±15kV ESD protection specifications for your application environment. Ensure the 24-pin SSOP footprint matches your PCB layout constraints before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple transmit lines but fewer receive lines. Verify that the system can accommodate four external 0.1μF capacitors for the charge pump. Consider the 120kbps maximum data rate limit and ensure it meets the baud rate requirements of the connected UART or microcontroller interface.

Drivers, Receivers, Transceivers Part Context

The MAX207E belongs to the broader MAX202E–MAX213E family of RS-232 transceivers. Unlike variants such as the MAX203E or MAX205E, the MAX207E does not include internal charge-pump capacitors and lacks shutdown control pins. It shares the same core architecture and ESD protection levels as other 'E' series devices but offers a distinct driver-to-receiver ratio optimized for specific multi-line transmission needs.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX207IDBR from Texas Instruments is a documented alternative offering identical electrical characteristics and pinout compatibility within the same 24-SSOP package format.
