Overview
The DS90LV031A is a quad CMOS differential line driver designed by Texas Instruments for applications that require ultra-low power dissipation and high data rates. This device utilizes Low Voltage Differential Signaling (LVDS) technology to support data rates exceeding 400 Mbps (200 MHz). It accepts low voltage LVTTL or LVCMOS input levels and translates them into low voltage (350 mV) differential output signals. The DS90LV031A is particularly useful in high-speed point-to-point interface applications, offering a low power alternative to high power pseudo-ECL devices.
