The MAX3223CAP+T is an RS-232 transceiver manufactured by Maxim Integrated. It operates from a supply voltage range of +3.0V to +5.5V, making it suitable for various applications. A key feature is Maxim's AutoShutdown™ technology, which reduces the supply current to as low as 1µA when no valid signal is detected on the receiver inputs. This power-saving feature activates when the RS-232 cable is disconnected or the connected peripheral's transmitters are off, and the system powers back on when a valid signal is reapplied.
The device requires minimal external components, needing only 0.1µF capacitors for 3.3V operation. It utilizes a proprietary high-efficiency dual charge-pump power supply and a low-dropout transmitter to deliver true RS-232 performance from a single supply. The MAX3223CAP+T is provided in a 16-pin SSOP package and is designed for surface mount applications.
This transceiver is part of the MAX3223 series, which includes other configurations like the MAX3221 (1-driver/1-receiver) and MAX3243 (3-driver/5-receiver). Its integrated charge pump circuitry simplifies power management in designs requiring RS-232 communication.
The supply voltage range is 3.0V to 5.5V, with nominal 3.3V operation.
The typical supply current is 1µA when AutoShutdown is active.
