NS3L500
3.3V, 8-Channel, 2:1 Gigabit
Ethernet LAN Switch with
LED Switch
The NS3L500 is a 8−channel 2:1 LAN switch with 3 additional
built−in SPDT switches for LED routing. This switch is ideal for
Gigabit LAN applications due to its low ON−state resistance and
capacitance giving the switch a typical bandwidth of 800 MHz. The
switch also has excellent ON−state resistance match, low bit−to−bit
skew, and low crosstalk among channels. The switch is bidirectional
and offers little or no attenuation of the high−speed signals at the
outputs.
This part can be used to replace mechanical relays in low−voltage
LAN applications that interface a physical layer over CAT 5 or CAT 6
unshielded twisted pair cable through an isolation transformer. The
NS3L500 is available in a 56−pin WQFN package and operates over
the extended −40°C to +85°C temperature range.
