Maxim Integrated MAX202ECUE+T RS-232 Interface IC

The MAX202ECUE+T from Maxim Integrated is a high-performance RS-232 transceiver IC, designed to meet the stringent requirements of EIA/TIA-232 and V.28/V.24 specifications, even at ±10% power supply voltages. This device is particularly suited for applications where ±12V is not available, and it operates with a single +5V power supply, using charge pump circuitry to generate the ±10V necessary for RS-232 signal levels.

This transceiver has a 2-driver and 2-receiver configuration, providing the essential lines necessary for full-duplex communications. The MAX202ECUE+T is capable of running at data rates up to 120kbps, making it a great choice for serial communication in a variety of applications, including point-of-sale systems, peripherals, and industrial control equipment.

The device comes in a 16-pin TSSOP package, which is an ideal choice for situations where space-saving is crucial without sacrificing performance. It also features a low-power shutdown mode that reduces power consumption and extends battery life in portable applications. The MAX202ECUE+T has an integrated charge pump that only requires four small 0.1µF external capacitors, which reduces the overall component count and board space.

Furthermore, the MAX202ECUE+T is designed with receivers that can handle up to ±30V input levels and ±8kV ESD protection on transmitter output and receiver input lines, ensuring robust performance in harsh electrical environments. This makes the device exceptionally reliable and safe to use in industrial settings where high voltage spikes may occur.

Key features of the MAX202ECUE+T include:

• Meets or Exceeds TIA/EIA-232-F and ITU V.28 Standards
• Operates from a Single +5V Power Supply
• Low-Power Shutdown Mode
• 120kbps Data Rate
• ±30V Receiver Input Levels
• ESD Protection for RS-232 I/O Pins (±15kV Human Body Model)
• Requires Only Four 0.1µF External Capacitors
• 16-Pin TSSOP Package

With its combination of high data rate, low power requirements, small package size, and high ESD protection, the MAX202ECUE+T is the perfect solution for any application requiring reliable RS-232 communications.
