Overview
The DS90LV047A device, produced by Texas Instruments, is a quad CMOS flow-through differential line driver. It is designed for applications that require ultra-low power dissipation and high data rates. This device utilizes Low Voltage Differential Signaling (LVDS) technology to support data rates exceeding 400 Mbps (200 MHz). The DS90LV047A accepts low voltage TTL/CMOS input levels and translates them into 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 device is available in surface mount SOIC and low profile TSSOP packages, making it suitable for various high-speed interface applications.
