Overview
The DS90LV047ATMTCX/NOPB is a quad CMOS differential line driver designed by Texas Instruments. This device is optimized for applications requiring ultra-low power dissipation and high data rates. It 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 flow-through pinout, which simplifies PCB layout, and includes a TRI-STATE function to disable the output stage, reducing power consumption to an ultra-low idle state of 13 mW typical at 3.3 V.
