Three driver and five receiver channels are supported for full duplex transmission with hardware flow control. The five 5-kΩ resistors are internal to the MAX3243E.
† C3 can be connected to VCC or GND
A. Resistor values shown are nominal.
B. Nonpolarized ceramic capacitors are acceptable. If polarized tantalum or electrolytic capacitors are used, they should be connected as shown.
