Overview
The DS90LT012ATMFX is a single-channel, low-voltage differential signaling (LVDS) line receiver produced by National Semiconductor. This device is designed for applications requiring ultra-low power dissipation, low noise, and high data rates. It operates from a single 3.3-V power supply, with a voltage range of 2.7 V to 3.6 V, and supports data rates in excess of 400 Mbps (200 MHz). The DS90LT012ATMFX translates low-voltage differential input signals into 3-V CMOS output levels, making it suitable for high-speed interface applications.
