current, connect FS to V or leave unconnected.  
CC_  
Shutdown Input. Ground for normal operation. When high, the power oscillator is  
disabled.  
SD  
Driver Input. With DE´ high (MAX1480A/B/C only), a low on DI´ forces output A  
low and output B high. Similarly, a high on DI´ forces output A high and output  
B low. Drives internal LED cathode through a resistor (Table 1 of Figure 1 for  
MAX1480A/B/C, Table 2 of Figure 2 for MAX1490A/B).

DI  
Driver-Enable Input. The driver outputs, A and B, are enabled by bringing DE´  
high. The driver outputs are high impedance when DE´ is low. If the driver out-  
puts are enabled, the device functions as a line driver. While the driver outputs  
are high impedance, the device functions as a line receiver. Drives internal  
LED cathode through a resistor (Table 1 of Figure 1).
