MAX207EENG

Drivers, Receivers, Transceivers Overview

The MAX207EENG is a single-supply 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 120kbps. The device operates on a single +5V supply (4.75V to 5.25V) utilizing an integrated charge pump to generate the required ±10V internal voltages, eliminating the need for external bipolar supplies. It requires four 0.1μF external capacitors for the charge pump circuitry. The component provides high electrostatic discharge protection of ±15kV via the Human Body Model. It is housed in a 24-pin SSOP package and supports an extended industrial operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables operation from a single +5V power supply without requiring external dual-voltage sources.
• Provides robust ±15kV ESD protection on all RS-232 inputs and outputs, ensuring reliability in harsh environments.
• Includes five independent drivers and three receivers for comprehensive serial communication interfacing.
• Features TTL/CMOS-compatible input thresholds with receiver hysteresis for clean signal transitions.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power serial connectivity
• Hand-held diagnostic tools and portable instrumentation
• Industrial control systems exposed to electrostatic discharge risks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ENG' against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure that the ordering information matches the exact package type and temperature grade required for the design. Cross-reference the datasheet revision date to validate current manufacturing status and compliance details before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and multiple transmit/receive channels are needed. The MAX207E variant specifically offers higher ESD tolerance compared to standard versions. Confirm that the application does not require a shutdown mode, as this specific configuration lacks power-down control pins. Verify that the 24-pin SSOP footprint aligns with the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E-MAX213E family of RS-232 transceivers designed for single-supply operation. The 'E' designation indicates enhanced ESD protection capabilities. The 'NG' suffix typically denotes the specific package style and lead finish, while 'MAX207' defines the internal driver and receiver count configuration within the broader product line.

Drivers, Receivers, Transceivers Replacement Considerations

The ADM207EARZ is a compatible alternative offering similar functionality with potentially different performance characteristics such as data rate or supply current. Verify pin-to-pin compatibility and ensure that the replacement meets the specific ESD and temperature requirements of the original design.
