DESCRIPTION:
compatible bus switches. The low ON resistance of the QS32X2861 allows
inputs to be connected to outputs without adding propagation delay and
without generating additional ground bounce noise. The QS32x2861 adds
an internal 25
reflection noise in high-speed applications. The Bus Enable (BEn) signals
turn the switches on.
