Overview
The DS90C031BTMX/NOPB is a quad CMOS differential line driver produced by Texas Instruments. This device is designed for applications that require ultra-low power dissipation and high data rates. It utilizes Low Voltage Differential Signaling (LVDS) technology to support data rates exceeding 155.5 Mbps (77.7 MHz). The DS90C031BTMX/NOPB accepts TTL/CMOS input levels and translates them into low voltage (350 mV) differential output signals, making it suitable for high-speed point-to-point interface applications.
