TI recommends keeping the signal lines as short and as straight as possible (see Figure 15). Incorporation of microstrip or stripline techniques are also recommended when signal lines are more than 1 in. long. These traces must be designed with a characteristic impedance of either 50-Ω or 75-Ω as required by the application. Do not place this device too close to high-voltage switching components because they may cause interference. Not all PCB traces can be straight and therefore some traces must turn corners. Figure 16 shows progressively better techniques of rounding corners. Only the last example (BEST) maintains constant trace width and minimizes reflections.
