MAX221ECAE Description

Short technical summary and product information.

The MAX221ECAE is an integrated circuit transceiver designed for EIA/TIA-232E and V.28/V.24 communications interfaces. It supports a single +5V supply operation, eliminating the need for a bipolar ±12V supply due to its integrated charge pump circuitry.

 

This transceiver features a data rate of 250kbps and operates with a supply voltage range of 4.5V to 5.5V. The operating temperature range is -40°C to 85°C. It is configured as a full duplex, 1/1 driver/receiver pair with 500mV of receiver hysteresis.

 

The device is housed in a 16-SSOP package, suitable for surface mounting. The MAX221ECAE is part of a family of line drivers and receivers intended for applications where printed circuit board space is critical and ±12V is not available. It also includes a low-power shutdown mode.

 

Key features include an integrated charge pump, enabling single supply operation, and a 5μW shutdown mode for reduced power requirements. The 16-SSOP package (0.209", 5.30mm width) facilitates compact designs.
