9.2.2.1 Design Requirements

TI recommends that the digital control pins SAI, SBI, SAO, and SBO be pulled up to V_CC or down to GND to avoid undesired switch positions that could result from a floating pin. Unused pins for the signal paths INA, INB, OUTAx, and OUTBx must be terminated with a 50-Ω resistor to ground to reduce signal reflections in high-speed applications.
