Overview
The DS90LT012AH is a single-channel, low-voltage differential signaling (LVDS) line receiver designed by Texas Instruments. It is optimized for applications requiring ultra-low power dissipation, low noise, and high data rates. The device operates from a single 3.3-V power supply, with a range of 2.7 V to 3.6 V, and supports data rates exceeding 400 Mbps (200 MHz). It translates low-voltage differential input signals to 3-V CMOS output levels, making it compatible with the ANSI TIA/EIA-644-A standard.
