NLAS7222B, NLAS7222C
High-Speed USB 2.0
(480 Mbps) DPDT Switches
ON Semiconductor’s NLAS7222B and NLAS7222C are part of a
series of analog switch circuits that are produced using the company’s
advanced sub−micron CMOS technology, achieving industry−leading
performance.
Both the NLAS7222B and NLAS7222C are 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).

Minimum and maximum values are guaranteed through test or design across the Recommended Operating Conditions, where
applicable. Typical values are listed for guidance only and are based on the particular conditions listed for section, where applicable.
These conditions are valid for all values found in the characteristics tables unless otherwise specified in the test conditions.
