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).
