Overview
The DS90LV031A, produced by Texas Instruments (formerly National Semiconductor), is a quad CMOS differential line driver designed 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 features a TRI-STATE® function, allowing the output stage to be disabled, which reduces the device to an ultra-low idle power state of 13 mW typical. This makes it an efficient alternative to high power pseudo-ECL devices for high-speed point-to-point interface applications.
