MAX3221/MAX3223/ MAX3243 +3V to +5.
5V RS-232 Transceivers with AutoShutdown General Description 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 onboard 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 MAX3221 is a 1-driver/1-receiver 16-pin SSOP version of the 20-pin 2-driver/2-...
