MAX3243CAI Description

Short technical summary and product information.

The MAX3243CAI is a high-efficiency RS-232 transceiver from Maxim Integrated, designed for applications requiring reliable serial communication. It operates from a single +3.0V to +5.5V supply, eliminating the need for a ±12V supply due to its integrated dual charge-pump power supply.

 

This transceiver configuration includes 3 drivers and 5 receivers, making it suitable for systems with multiple serial ports. A key feature is Maxim's AutoShutdown™ technology, which reduces supply current to as low as 1µA when no valid signal is detected on the receiver inputs. This power-saving mode is automatically enabled after 30µs of inactivity and can also be software-controlled.

 

The MAX3243CAI is available in a 28-pin SSOP package, designed for surface mounting. Its robust design and power-saving features make it ideal for battery-powered equipment, hand-held devices, and other portable diagnostic equipment where power efficiency is critical.
