MAX202IN

Drivers, Receivers, Transceivers Overview

The MAX202IN is a dual RS-232 line driver and receiver manufactured by Texas Instruments, designed for asynchronous communication controllers. It operates from a single +5V supply using internal charge pumps to generate ±10V output levels, eliminating the need for external negative voltage sources. The device features two drivers and two receivers, supporting data rates up to 120 kbps. It provides ±15-kV electrostatic discharge (ESD) protection on all pins, including the serial port connection ground pin. The component is housed in a 16-pin DIP package and functions within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry converts a single +5V supply into the required ±10V RS-232 signal levels without external negative voltage rails.
• Provides robust ±15-kV ESD protection across all pins, including the ground pin, ensuring reliability in high-interference environments.
• Supports full-duplex communication with two independent drivers and two receivers for standard RS-232 interfaces.

Drivers, Receivers, Transceivers Applications

• Connecting microcontrollers or DSPs to PC serial ports for data exchange.
• Industrial control systems requiring reliable serial communication in electrically noisy environments.
• Embedded systems interfacing with legacy RS-232 peripherals such as modems or printers.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'IN' against the manufacturer's current datasheet to confirm package type and availability status. Ensure the ordering part number matches the required lead-free and RoHS compliance specifications. Cross-reference the manufacturer's official documentation for any recent product change notifications or lifecycle updates before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-232 transceiver is needed with integrated ESD protection and single-supply operation. Compare power consumption and data rate requirements against similar devices like the MAX202IDR if surface-mount packaging is preferred. Confirm that the DIP package fits the target PCB layout constraints and thermal management requirements.

Drivers, Receivers, Transceivers Part Context

The MAX202 series is a widely used family of RS-232 transceivers known for their simplicity and robustness. The MAX202IN specifically denotes the industrial temperature grade version in a 16-pin DIP package. It serves as a direct replacement for older RS-232 interface chips that required multiple power supplies, simplifying system design for embedded applications.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the MAX202IDR (SOIC package) and MAX202IPW (TSSOP package). Verify electrical characteristics and package dimensions before substitution. Other compatible parts may include the MAX202E variants, but always consult the latest datasheets for functional equivalence.
