MAX3243ECWI Description

Short technical summary and product information.

The MAX3243ECWI is a 3V-powered EIA/TIA-232 and V.28/V.24 communications interface transceiver. It offers high data rate capabilities and enhanced electrostatic discharge (ESD) protection, rated to ±15kV using IEC 1000-4-2 Air-Gap Discharge and ±15kV using the Human Body Model. This transceiver achieves a low supply current of 1µA with Maxim's AutoShutdown™ feature, saving power when the RS-232 cable is disconnected or peripherals are off.

 

Designed for applications requiring a complete serial port, the MAX3243ECWI includes 3 drivers and 5 receivers. It operates from a +3.0V to +5.5V supply and maintains true RS-232 performance at data rates of 250kbps. The device is available in a 28-SOIC package and is suitable for surface mount applications.

 

Key electrical characteristics include a supply voltage range of 3V to 5.5V, an operating temperature range of 0°C to 70°C, and a receiver hysteresis of 300mV. The transceiver supports full duplex communication.

 

This component is ideal for battery-powered equipment, handheld devices, notebook computers, and peripherals where space and power efficiency are critical.
