MAX3221CUE+ Product Details
The MAX3221/MAX3223/MAX3243 achieve 1μA supply current with Maxim’s revolutionary AutoShutdown feature. When the MAX3221/MAX3223/MAX3243 do not sense a valid signal level on their receiver inputs, the on-board power supply and drivers shut down. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripheral are turned off. The system turns on again when a valid level is applied to any RS-232 receiver input.
The MAX3221/MAX3223/MAX3243 require only 0.1μF capacitors in 3.3V operation, and can operate from input voltages ranging from +3.0V to +5.5V.
A proprietary, high-efficiency, dual charge-pump power supply and a low-dropout transmitter combine to deliver true RS-232 performance from a single +3.0V to +5.5V supply.
The MAX3221CUE+ is a 1-driver/1-receiver 16-pin SSOP version of the 20-pin 2-driver/2-receiver MAX3223.
The MAX3243 is a 3-driver/5-receiver with a complementary always-active receiver for external monitoring in a variety of 28 pin packages. Please see order information table for package offerings.
