Note1: Voltage is ground referenced.
Note2: However, do not exceed 6V.
Note3: PCB condition 76.2 x 114.3 x 1.6 mm, Cu 30% (SEMI conforming)
Note4: The power dissipation decreases the reciprocal of the saturated thermal resistance (1/ Rth(j-a)) for each
Note1: Please refer to page 16 for details of the error detection.
Note2: If the device is connected in a cascade and the tr/tf of the clock waveform increases due to deceleration of the clock waveform,
