General Description
The SUM7227 is 2 to 1 port analog switches. Their wide bandwidth and low bit-to-bit skew allow them to
pass high-speed differential signals with good signal integrity. Each switch is bidirectional and offers little
or no attenuation of the high-speed signals at the outputs. Industry-leading advantages include a propagation
delay of less than 250 ps, resulting from its low channel resistance and low I/O capacitance. Their high channel
to-channel crosstalk rejection results in minimal noise interference. Their bandwidth is wide enough to pass
High-Speed USB 2.0 differential signals (480 Mb/s).
