Multichannel RS-232 Drivers/Receivers _______________Detailed Description The MAX220–MAX249 contain four sections: dual charge-pump DC-DC voltage converters, RS-232 dri- vers, RS-232 receivers, and receiver and transmitter enable control inputs. Dual Charge-Pump Voltage Converter The MAX220–MAX249 have two internal charge-pumps that convert ...

... This operation conserves system power. Negative Threshold—MAX243 The MAX243 is pin compatible with the MAX232A, differ- ing only in that RS-232 cable fault protection is removed on one of the two receiver inputs. This means that control lines such as CTS and RTS can either be driven or left floating without interrupting communication ...
