Overview
The DS90LV047A device, produced by Texas Instruments, is a quad CMOS flow-through differential line driver designed for applications requiring ultra-low power dissipation and high data rates. It supports data rates in excess of 400 Mbps (200 MHz) using Low Voltage Differential Signaling (LVDS) technology. The device accepts low voltage TTL/CMOS input levels and translates them to low voltage (350 mV) differential output signals. It features a TRI-STATE function to disable the output stage, reducing power consumption to an ultra-low idle state of 13 mW typical. The flow-through pinout simplifies PCB layout, and the device is available in surface mount SOIC and low profile TSSOP packages.
