Product Introduction

Overview

The DS90LV049H is a dual CMOS differential line driver-receiver pair designed by Texas Instruments. This device is optimized for applications requiring ultra-low power dissipation, exceptional noise immunity, and high data throughput. It supports data rates in excess of 400 Mbps using Low Voltage Differential Signaling (LVDS) technology. The DS90LV049H operates from a single 3.3-V power supply and is available in a low-profile 16-pin TSSOP package, facilitating easy PCB layout with its flow-through pinout.
