Overview
The DS90LV047ATMTCX-NS is a quad CMOS differential line driver designed by Texas Instruments (now part of the National Semiconductor portfolio). This device is optimized 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 DS90LV047A accepts low voltage TTL/CMOS input levels and translates them to low voltage (350 mV) differential output signals, conforming to the TIA/EIA-644 LVDS standard.
