Overview
The DSLVDS1047PWR is a 3.3-V LVDS (Low Voltage Differential Signaling) quad channel high-speed differential line driver produced by Texas Instruments. This device is designed for applications that require ultra-low power dissipation and support high data rates. It operates at signaling rates up to 400 Mbps (200 MHz) and is compatible with existing 5-V LVDS receivers. The DSLVDS1047PWR accepts low voltage TTL/CMOS input levels and translates them into low voltage (350 mV) differential output signals, making it suitable for various high-speed point-to-point interface applications.
