The SN65LVDS250 and SN65LVDT250 are 4x4
nonblocking crosspoint switches in a flow-through
pin-out allowing for ease in PCB layout. Low-voltage
differential signaling (LVDS) is used to achieve a
high-speed data throughput while using low power.
Each of the output drivers includes a 4:1 multiplexer
to allow any input to be routed to any output. Internal
signal paths are fully differential to achieve the high
signaling speeds while maintaining low signal skews.
The SN65LVDT250 incorporates 110- Ω termination
resistors for those applications where board space is
a premium.
The SN65LVDS250 and SN65LVDT250 are
characterized for operation from -40 ° C to 85 ° C.
