USAGE PRECAUTIONS
Slave Address (94h) Setting
When slave address used, input must left open circuit. this case, external resistor should connected shown figure reduce risk malfunction I2C-BUS interface large external spikes other noise invaded from outside. recommended value 10k.
Direct Input Mode
direct input mode, signal connected input without capacitor. However, input voltage range varies with mode setting, hence signal must appropriately biased corresponding mode. recommended LOW-level voltage (VL) HIGH-level voltage (VH) each mode shown table (see figure 5V). input voltage exceeds these limits, careful because harmonic distortion occur output signal. (For preventing device breakdown, input bottom voltage voltage should within absolute maximum ratings.)
