www.DataSheet4U.com DS90LV049H High Temperature 3V LVDS Dual Line Driver and Receiver Pair September 2005 DS90LV049H High Temperature 3V LVDS Dual Line Driver and Receiver Pair General Description The DS90LV049H is a dual CMOS flow-through differential line driver-receiver pair designed for applications requiring ultra low power dissipation, exceptional noise immunity, and high data throughput. The device is designed to support data rates in excess of 400 Mbps utilizing Low Voltage Differential Signaling (LVDS) technology. The DS90LV049H drivers accept LVTTL/LVCMOS signals and translate them to LVDS signals. The receivers accept LVDS signals and translate them to 3 V CMOS signals. The LVDS input buffers have internal failsafe biasing that places the outputs to a known H (high) state for floating receiver inputs. In addition, the DS90LV049H supports a TRI-STATE function for a low idle power state when the device is not in use. The EN and EN inputs are ANDed together and control the TRI-STATE outputs. The enables are common to all four gates.
