DS90C031TMX

Overview

The DS90C031TMX is a four-channel CMOS differential line driver utilizing Low Voltage Differential Signaling (LVDS) technology. It converts TTL/CMOS input levels into low-voltage differential outputs with a typical amplitude of 350 mV. The device supports data rates exceeding 155.5 Mbps and features TRI-STATE functionality to disable outputs, reducing load current and achieving an ultra-low idle power consumption of typically 11 mW. Designed for high-speed point-to-point interfaces, it serves as a low-power alternative to pseudo-ECL devices.
