DESCRIPTION

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-W 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.
