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- 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.
