Beschreibung : MAX220 Thru MAX249, MAX232, +5V-Powered, Multichannel RS-232 Drivers/Receivers – Maxim Integrated / Battery-Powered RS-232 Systems
The MAX220 thru MAX249, MAX232 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available.
The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for applications where printed circuit board space is critical.
Applications/Uses
1. Battery-Powered RS-232 Systems
2. Interface Translation
3. Low-Power Modems
4. Multidrop RS-232 Networks
5. Portable Computing
The MAX220–MAX249 contain four sections: dual charge-pump DC-DC voltage converters, RS-232 drivers, RS-232 receivers, and receiver and transmitter enable control inputs.
MAX232 Low-Power Receive Mode
The low-power receive mode feature of the MAX223, MAX242, and MAX245–MAX249 puts the IC into shut down mode but still allows it to receive information. This is important for applications where systems are periodically awakened to look for activity. Using low-power receive mode, the system can still receive a signal that will activate it on command and prepare it for communication at faster data rates. This operation conserves
system power.
